So having watched DD over the last couple of years, we've all seen him stick in the pocket when he could have run. My hunch is that he knows that he'll always have that to fall back on BUT he wants to be a pocket passer similar to Calvillo. It's hard to argue with when you see that Calvillo has 18 years in the league. Even Burass is keeping to the pocket more so now and he has 13 years in the league.
DD is more effective rollin' to the side and running but I feel he wants to be a pocket passer, keep the injuries down. Should have a long career which is good for us.
