RICHMOND, Va. (AP) - Kyle Shanahan says he understands Robert Griffin III's frustration.
The Washington Redskins offensive coordinator said Thursday that he's also frustrated that he doesn't have his top quarterback at full-go for practice, but that it's for the best that Griffin not try to do too much while returning from reconstructive knee surgery.
Griffin had some 11-on-11 work for the second day in a row, taking 21 snaps and completing 14 of 15 passes against a scout team defense.
Shanahan says it's now a matter of Griffin ``getting the rust off'' and getting as much work as possible without risking further damage to the knee.
Shanahan says he and his father, head coach Mike Shanahan, have had ``constructive arguments'' over the years, but he thinks they've made each other better.
