PHILADELPHIA (AP) - Chip Kelly's high-octane Eagles offense needed time to find its power surge, taking until Michael Vick's 61-yard touchdown pass in the second half to push the needle all the way to full.
It's the defense that had nothing in the tank.
Kelly has molded the Eagles into an offensive dynamo, with Vick, DeSean Jackson and LeSean McCoy all posting numbers fit for a video game eruption. The only thing that can slow the Eagles is a defense that can't stop any team.
Philip Rivers threw three touchdown passes to Eddie Royal, and Nick Novak kicked a 46-yard field goal with 7 seconds left to lead the San Diego Chargers past the Eagles 33-30 on Sunday, spoiling Kelly's home debut.
On Philly's turf, the Chargers (1-1) looked more like the Eagles' ideal offense.
They racked up 539 yards, held the ball for 40:17 and sped things up.
Rivers was never under any serious pressure and completed his first 10 passes. He finished 36 of 47 and was sacked only once, a week after Washington's Robert Griffin III completed 30 of 49 passes for 329 yards.
``There ain't any safeties on the street, I can tell you that,'' Kelly said. ``We'll play with the ones we've got.''
The Eagles (1-1) have allowed six touchdowns in the last six quarters, the kind of porous defense that can negate even the most explosive plays out of the offense. With former coach Andy Reid and the Kansas City Chiefs in town Thursday, there's little time to shore up the D.
``You're not going to find anybody at this point in time that's hanging out on the street corner that's going to be able to play safety for you,'' Kelly said. ``We've got to coach them better, and we've got to put them in position to make plays.''
The teams combined for 1,150 total yards.
Vick threw for a career-best 428 yards and two touchdowns and ran for a score. Jackson caught nine passes for 193 yards and a TD. McCoy combined for 167 yards rushing and receiving.
``It's tough. Maybe we needed to score 37 points,'' Vick said.
Well, at least 34.
Kelly gave the NFL a huge jolt in his coaching debut last week against Washington, cramming 53 plays into a 30-minute first half. The Eagles took a 26-point lead in the third quarter and held on for a 33-27 win over the defending NFC East champs.
Philadelphia's frenetic plays didn't help them pile up the points Sunday, at first. Vick connected with Riley Cooper for a 13-yard TD late in the first half, then hit Jackson for the 61-yarder in the third that tied the game at 20.
The Eagles took a 27-23 lead when Vick ran in from the 2, but the defense couldn't hold it.
Kicker Alex Henery allowed the ball to slip through his hands when Fozzy Whittaker fumbled on the kick return, and the Chargers started at the Eagles 39. A few plays later, Rivers tossed a 15-yard TD pass to Royal for a 30-27 lead.
``It seemed like they were on to every play and every check that we made,'' Eagles cornerback Cary Williams said. ``They understood what was going on. We were not able to get off the field when we needed to.''
Williams was called for a pair of pass interference penalties.
Antonio Gates led the Chargers with 124 yards receiving, Malcom Floyd had 102 and Royal added 90. The Chargers had just 80 yards rushing against the Texans but ran for 126 yards against the Eagles.
``The whole defense needs work,'' defensive coordinator Bill Davis said. ``We have to get off the field and get the offense the ball.''
The Chargers got good news after the game when they learned Floyd was fine after leaving on a stretcher with a neck injury on a hard hit by DeMeco Ryans and Nate Allen on the first play from scrimmage after halftime.
``All the tests right now look good, so it's great for the organization to go out and get a win for Malcom,'' coach Mike McCoy said.
NOTES: Royal has five TDs on 10 catches in two games. ... Chargers rookie LB Manti Te'o didn't play because of a sprained right foot that he injured in a preseason game Aug. 8. ... Eagles starting CB Bradley Fletcher was sidelined because of a concussion.
