Pete Carroll and Bill Belichick have a different philosophy on their defensive backs, and everyone can decide for themselves. Of course if any of the midgets Wheatly, Butler, Wilhite, Arrington had worked out, BB would probably have 5 HC rings not just 3.
I don't know why you think he has better gamespeed than his combine 40, I mean I understand deltas do exist but what is the basis of your thinking?
Did you see him running side by side Andre Johnson or something?
Dennard was a steal cause he punched a cop in the face the week before the draft. Everyone knows he had the talent for the top 3 CB in the draft. He probably is a really great #2 but I don't see how he can physically (height or speed) keep up with the burners in a dome or compete on these jump balls that are always thrown to give the elites a chance to come down with it or at least draw a PI call.
