ASHBURN, Va. -- One of the latest charges against Washington Redskins quarterback Robert Griffin III is that he’s not receptive to coaching. It’s not the first time I’ve heard that, but I’ve also heard from others who like working with him. And I’ll repeat this line: I didn’t hear these charges at this time last season. But it was noteworthy that when asked about how coachable Griffin is during his Wednesday press conference, Redskins coach Mike Shanahan answered the question -- without saying yes or no.via - NFL Nation
