RG3 said on a show yesterday that he worked out with Pickett and he was extremely impressed with his football knowledge,
I'm sure RG3 knows "football knowledge" when he sees it!
I'm reserving judgment until I hear what Ryan Leaf thinks, though.
Obviously Pickett has looked just fine so far even without much protection from his line, and he should only get better but we'll have to see what happens when (if) he gets into a game that counts.
