I think what the Pro-Denard crowd is missing is that we don't want him throwing the football. He is lousy at it anyway but even if he was good, why bother with it. We want Griffin throwing the ball not Banks, Denard, Portis or anybody else.
If we want WR, fine. If we want RB, fine draft one but don't draft Denard, who is not either because he has the opportunity to pass every so often. You can find an Antwan Randle El anywhere in the draft even as UDFA and most likely would find one that can catch better than DR too. It would be mind boggingly foolish to waste a 4th on him when we already run too much option and trickery on offense.
We don't know if he can catch consistently. We don't know if he can handle the abuse a RB does. Its just not worth it for essentially a gimmick player. He has elite speed/running ability and can throw a little. I just don't see where he fits into our offense that isn't to RG3's detriment.
Griffin has elite talent as a passer, don't take away his reps and give them to Denard just because you can.
