Carter tied for the most pressures by a rookie defender in the last five years. Passing on massive talent at our worst position because he looked lazy in one workout is going to look like all those teams that said "What about DK's three-cone?!?".
Maybe, time will tell.
But there's a fatal flaw in the logic that "player X we didn't draft is doing awesome, and therefore would be awesome here."
Dozens of other factors go into a player's success, or failure. Carter literally went to the best case scenario he could have ever dreamed of. SB ready team, one of the best if not THE best D-line in the entire league, and a couple old friends on the line to keep him on the straight and narrow.
Let's be honest, if he was here? He'd be double teamed all game cause the rest of the line is garbage. Doesn't mean we probably should have drafted him, but it does mean what he does in Philly doesn't = what he'd do here.
