Surprised nobody has challenged you yet and said Trey Flowers. But I agree with you. He's very easy to account for given the way he's wasted on passing downs rushing inside. I think he'd do a lot more damage if he took on tackles on the edge as he's a very good bull rusher. I can't imagine he likes doing that as every defensive end wants to rush the edge. Wouldn't shock me if he walks based on how he's used in the scheme.
I'd throw Colvin in there. He allowed AD to play more coverage and eliminate TE's. When Colvin got hurt, AD was getting to the QB but TE's were starting to get open like that long catch and run by Kevin Boss in the Super Bowl.
