Alright, it is probably getting old, but we are going to say it again. Sorry.

Don't fill your team full of rookies!

It isn't a bad idea to get a few rookies on your team, but filling your roster with rookies normally doesn't lead to victories. And there probably are a lot of examples of this happening from past leagues you have participated. Don't be that owner.

Some rookies will make an impact, but be discrete with your choices. Quarterbacks normally don't do much (Matt Ryan did last season but his stats weren't off the charts), but running backs, receivers and tight ends bring some fantasy value. The key is for you to figure out the players most likely to make a consistent, positive impact throughout the season.

Below is a look at some of the top offensive rookies from this year's draft. The rookies are broken out by position and ranked for the coming season.

QUARTERBACKS

1. Mark Sanchez (first round), Jets. Sanchez will compete with Kellen Clemens for the starting job. Sanchez has a good chance to win the job, though. Clemens hasn't done a whole lot when given the chance in the past. Sanchez only started 16 games in college, which is a concern, but he was very good in those 16 games. Sanchez comes from a pro style offense and rarely made mistakes in college. Sanchez doesn't have a rocket for an arm, but it is solid enough. He reads defenses well and can move around the pocket to avoid the rush and make plays.

2. Matthew Stafford (first round), Lions. The Lions aren't just going to hand Stafford the starter's job this season despite taking him with the first pick in the draft. He could be eased into action, serving as Daunte Culpepper's backup early in the season. Stafford has the intangibles to be a top NFL starter. He has a rocket for an arm, is mobile and strong for a quarterback. He does tend to force some throws at times because of his arm strength, though.

3. Josh Freeman (first round), Bucs. The Bucs took Freeman in hopes of finding their franchise quarterback. He isn't a sure thing, but the talent is there. Freeman needs some seasoning, but the Bucs will give him a shot to start this season. He has all the tools to be a great NFL quarterback. He has a great arm, can make plays with his feet and has the size and strength to hold up over the course of a season. Freeman needs to improve his decision making and accuracy, though.

4. Pat White (second round), Dolphins. White could be the new wave of NFL quarterbacks. He should get plenty of work in the Dolphins Wildcat formation this season. White is a very athletic quarterback. He isn't very big, but runs well and will make defenders miss. He also has a pretty good arm and was fairly accurate in college. He will struggle with accuracy on the deep ball, though. White could eventually make the move to receiver because of his lack of size, but the Dolphins should continue to use him as a quarterback this season, getting him some action off their bench.

5. Tom Brandstater (sixth round), Broncos. Brandstater won't challenge to start this season, but gives the Broncos a young quarterback to develop the next few seasons. He could eventually end up the starter for new coach Josh McDaniels. Brandstater is a big kid (6-5), but also moves around the pocket pretty well despite his size. He has a solid arm and does fairly well on short or intermediate throws. He has some struggles with deeper passes, though, and will need to improve his reads.

6. Stephen McGee (fourth round), Cowboys. McGee is more of a project for the Cowboys, but they hope he can be their No. 2 in another season or two, backing up Tony Romo. McGee has a lot of skill, but is pretty raw. He has a great arm, but lacks solid mechanics, which makes him inconsistent. McGee is very tough, though, and has shown pretty good touch on deep passes.

7. Rhett Bomar (fifth round), Giants. Bomar has the skill set to be a decent pro quarterback. He has some work to do, though. Bomar is an accurate passer on the short to intermediate throws. He has a so-so arm and fairly quick release. He needs to do a better job of reading defenses and on the deep ball. He is likely to be the Giants No. 3 quarterback this season, but could be their top backup in a season or two.

8. Nate Davis (fifth round), 49ers. Davis probably won't get a chance to start this season, but with not much in front of him, Davis could get a legit chance to start in another season or two. Davis isn't a big quarterback, but has a solid arm and good release. He also does a good job of moving around the pocket and avoiding the rush. Davis could struggle picking up a pro offense. He came from a simple system and struggled against better competition in college.

9. Curtis Painter (sixth round), Colts. Painter didn't play much his senior season because of a shoulder injury, but did enough before that for the Colts to take a chance on him. He'll compete to be the Colts No. 3 quarterback this season. Painter has a pro arm and showed good accuracy in college. He doesn't do well under pressure, though, and will force some throws in those situations.

10. Keith Null (sixth round), Rams. Null is a project for the Rams. He came from a very small school, but was a productive college player. He was very accurate and posted huge numbers. Null doesn't have a great arm, though, and could take some time adjusting to a pro style offense (comes from a spread offense).

RUNNING BACKS

1. Knowshon Moreno (first round), Broncos. Moreno is an explosive back with big-play ability. He has great moves in the open field and is an exceptional receiver for a running back. Moreno should be a great fit for the Broncos offense. He should start from day one for the Broncos. First-year coach Josh McDaniels does have a history of rotating backs, though, so Moreno could get a little less time than your typical starter.

2. Chris Wells (first round), Cardinals. The Cardinals get their No. 1 back in Wells. He is a powerful back that does a great job of running between the tackles. He also is big enough to move the pile. Wells has plus speed despite his size and can make tacklers miss with his good moves in the open field. And Wells is an above-average blocker for a rookie, which will keep him on the field in the Cardinals pass-heavy offense. If Wells has a knock, he had a hard time staying healthy during his college career.

3. LeSean McCoy (second round), Eagles. The Eagles hope McCoy is the eventual replacement for Brian Westbrook. McCoy has the skill set to be a top back in the Eagles system. He is an elusive back with very good hands. He also has plus speed. McCoy should be a great backup to Westbrook, having similar ability. McCoy isn't very big, though, and might need to bulk up to be an every-down back. His outstanding receiving skills should get him plenty of playing time his rookie season.

4. Donald Brown (first round), Colts. Brown could be the starter before long, especially if Joseph Addai gets hurt or struggles. For now, expect Brown to backup Addai and get a few more carries than your typical backup. Brown has top speed and great moves. He should be a great fit for the Colts running scheme. Brown does lack some size, though, which could hurt his chances to start early in his career. Brown also has solid hands, which is another plus for playing in the Colts system.

5. Glen Coffee (third round), 49ers. Coffee gives the 49ers some punch at running back. He should be a nice compliment to Frank Gore. Coffee is a physical runner that isn't afraid to run over would-be tacklers. Coffee also has pretty good speed for a back with his size. He does a good job of hitting the hole quickly. Coffee has an upright running style, though, which can lead to injury. He should be the top backup to Frank Gore this season and get plenty of chances in a run-heavy 49ers offense.

6. Shonn Greene (third round), Jets. Greene is the future at running back for the Jets. And the future could be this season with Thomas Jones not getting any younger. Greene is a powerful back that does a good job of running between the tackles. He hits the hole in a hurry. The knocks on Greene are he doesn't have top speed and had few receptions in college. He'll need to work on his hands and in blitz pickup if he hopes to be an every-down back in the NFL.

7. Andre Brown (fourth round), Giants. The Giants hope Brown can replace Derrick Ward, which is very possible. Brown is even similar to Ward in build. Brown is pretty tall and solid, and more of a straight-ahead runner than a slasher. He isn't a home run threat, but a good between the tackles runner that will hit the hole in a hurry. He'll probably serve as the No. 3 back for the Giants this season.

8. Gartrell Johnson (fourth round), Chargers. Johnson is a different type of runner for the Chargers. He is more of a between the tackles runner, churning out the tough yards. Johnson could be a fine compliment to LaDainian Tomlinson and Darren Sproles, using a different running style. He also could be a fine short-yardage option for the Chargers. Johnson isn't much of a home run threat, though, because of just so-so speed for the running back spot.

9. James Davis (sixth round), Browns. Davis could step into a backup role with the Browns his rookie season. He has the attributes to be a fine compliment to Jamal Lewis. Davis has plus speed and shifty moves it the open field. He can break through a hole in a hurry. He needs to work on his blocking if he ever hopes to be an every-down back.

10. Frank Summers (fifth round), Steelers. The Steelers could finally have their short-yardage specialist in Summers. Summers is a small back (5-9), but packs a punch at over 240 pounds. He is a strong back that will hit the hole in a hurry. Summers doesn't dance around behind the line. He also has pretty good hands out of the backfield. Summers lacks breakaway speed, though, which could lead to him moving to fullback.

WIDE RECEIVERS

1. Michael Crabtree (first round), 49ers. Crabtree should become a starter from day one for San Francisco, a team starved for help at receiver. Crabtree is a pretty polished product for a rookie. He has amazing hands, runs solid routes and is just a playmaker. His only big knock is he lacks elite speed. Crabtree also had a stress fracture in his foot, which is something to keep an eye on in minicamp.

2. Hakeem Nicks (first round), Giants. Nicks should be a good replacement for the departed Plaxico Burress. He is a similar receiver to Burress. Nicks is a big target with great hands and athletic ability. He isn't quite as tall as Burress, but has long arms and good strength. His only knock might be his speed, which is solid but not off the charts. Nicks has a chance to step into a starting role right away for the Giants.

3. Percy Harvin (first round), Vikings. Harvin just made plays in college, which is why the Vikings overlooked some of his off the field concerns. Harvin made plays from all over the field in college - as a receiver, running back and return man. He has top speed and great moves in the open field. He should be a great fit for the slot for the Vikings, playing between Bernard Berrian and Sidney Rice. Harvin probably lacks the size to be a starter in the NFL, but his overall ability will get him on the field plenty.

4. Jeremy Maclin (first round), Eagles. Maclin gives the Eagles a big-play threat at receiver. He has top speed and a knack for making big plays. Maclin also is a very good return man. He does need to work on his route running some, though. The Eagles should find a way to get the ball in his hands his rookie season. Maclin might not start, but the Eagles throw often, which should get Maclin involved on a weekly basis.

5. Kenny Britt (first round), Titans. Britt gives the Titans a much needed playmaker at receiver. He is a big target that runs good routes and is capable of making a big-play in a hurry because of his top speed and ability to take it to another level in a hurry. Britt has good hands, but does suffer from the occasional drops, which plagued him at times in college. He has a chance to start right away in Tennesse, though, since they don't have much at receiver. And his skill set seems a good fit for the Titans offense, especially since Britt is a willing blocker.

6. Brian Robiskie (second round), Browns. Robiskie isn't a huge home run threat, but should be a top possession receiver in the Browns offense. He is a physical receiver because of his size and strength. He should step right into a starting role for the Browns. Robiskie runs great routes and has plus hands. He catches nearly everything thrown his way. Robiskie should be a fine compliment to big-play receiver Braylon Edwards.

7. Juaquin Iglesias (third round), Bears. Iglesias could make an immediate impact with the Bears. He is one of the more polished rookie receivers. Iglesias should have the inside track for the Bears No. 3 receiver spot. He is a good fit for the slot. Iglesias isn't a speed demon, but is quick with good moves and plus hands. He also runs good routes.

8. Darrius Heyward-Bey (first round), Raiders. Heyward-Bey was the first receiver taken in this year's draft. He was taken more so for his ability and upside than his production on the field. Heyward-Bey was the fastest receiver at the combine, which made owner Al Davis make him their player. Heyward-Bey will be an immediate deep threat for the Raiders, but still needs a lot of work in other areas of his game. He is a great straight-line runner, but lacks polish on other routes and his hands can be suspect at times. Heyward-Bey is a bit of a project, but should get immediate playing time and challenge to start as the Raiders lack quality options at receiver.

9. Austin Collie (fourth round), Colts. Collie was a productive player in college and seems a good fit for the Colts offense. He isn't going to burn you deep, but Collie runs solid routes and has plus hands. He does a good job of finding a soft spot in the secondary. He could be the No. 3 receiver for the Colts as soon as this season.

10. Brandon Tate (third round), Patriots. Tate suffered a torn ACL and MCL during his senior year in college, which likely contributed to him slipping to the third round of the draft. But Tate has a lot of ability. Not only can he contribute at receiver, but Tate can be a real asset on special teams as a return man. Tate is a solid open-field runner with pretty good speed. He doesn't have a ton of experience at receiver, so he has some work to do to get consistent playing time.

TIGHT ENDS

1. Brandon Pettigrew (first round), Lions. Pettigrew is a huge tight end with plus hands and top athleticism. His size makes him a tough cover for opposing defenses. Pettigrew also is a willing blocker, which is a plus for the Lions running game. He probably needs to tighten up his route running, but should improve that over time and with more experience.

2. Jared Cook (third round), Titans. Cook wasn't much of a blocker in college, but he caught passes and ran routes like a receiver. He is a top athlete with plus speed and decent hands. He'll be able to stretch defenses down the middle because of his speed. Cook's lack of experience blocking, though, will keep him off the field at times. Cook probably won't start, but will be used in many passing situations.

3. Chase Coffman (third round), Bengals. Coffman has some durability concerns, but he gives the Bengals a huge target at tight end (6-6). He doesn't have top speed for the tight end position, but has great hands and is a very good athlete. Coffman has a chance to step right into a starting role with the Bengals. He will need to prove himself as a blocker, though, if he hopes to land that starting job.

4. Shawn Nelson (fourth round), Bills. Nelson gives the Bills a legit pass-catching tight end. He is a big target (6-5) with plus speed and solid athleticism. Nelson should be able to cause mismatches in the middle of the field. He still needs to bulk up some to improve his blocking skills. He could struggle some his first year or two in the league blocking.

5. Cornelius Ingram (fifth round), Eagles. Ingram missed his last year of college because of a torn ACL, but should be healed for the start of this season. The Eagles overlooked the injury, because Ingram is a top athlete with very good hands. His speed wasn't elite before the injury, though, so it will be interesting to see how he responds this season. Ingram also needs to improve his blocking if he ever hopes to be a starting tight end. The Eagles rotate tight ends and get them involved in the offense, so Ingram has a chance to earn a lot of playing time in a pass-happy offense.

6. Davon Drew (fifth round), Ravens. With Todd Heap getting older, the Ravens hope Drew will be their next starting tight end. Drew is an athletic tight end with plus hands. He also runs good routes. He might lack the size to be a true starting tight end, though. He is a little leaner than your usual tight end.

7. Travis Beckum (third round), Giants. Beckum is a bit small for the tight end position, but was a productive player in college. He has very good speed and does a good job of stretching defenses in the middle of the field. Beckum also has pretty good hands. He'll likely be the top backup in New York this season.

8. James Casey (fifth round), Texans. The former baseball prospect is older than most rookies (25 shortly after the season starts), but is an athletic player with upside. The Texans took him based on his potential because he saw little work as a tight end in college. Casey played seven different positions in college, making him a versatile option for the Texans. He could line up all over the field. Casey is an athlete, but could take some time adjusting to the NFL.

9. Johnathan Nalbone (fifth round), Dolphins. Nalbone played at a small school in college (Monmouth), but has good overall skills at tight end. Not only is he a solid blocker, but also does pretty well in the passing game. He has pretty good hands and enough speed to make plays downfield. Nalbone doesn't do anything outstanding, but also isn't too weak in any one area.

10. Zach Miller (sixth round), Jaguars. Miller is a former quarterback that made the switch to tight end in college. He has a lot of potential, though. Miller is very fast for the position and is a top athlete. He could be a load to cover over the middle. Miller doesn't have much experience blocking and comes from a small school, which could make his transition tough.

KICKERS

1. Ryan Succop (seventh round), Chiefs. Succop will be the favorite for the Chiefs kicking duties. He is a talented option. Succop has an NFL leg and is extremely accurate on kicks of 40 yards or less. Succop does struggle a bit with his accuracy on long-distance kicks, though, so he'll need to improve on that if he hopes have a long NFL career.

2. David Buehler (fifth round), Cowboys. The Cowboys brought in some competition for starter Nick Folk. Buehler has a very strong leg and is accurate, which are two obvious pluses for him. He also is a great athlete that is well put together. He actually practiced some at safety in college. So he isn't afraid to make a tackle or mix it up with his opponents. Buehler might not win the kicking job, but has a good chance to be the kickoff specialist, especially since he can tackle.
