There are plenty of smaller players who are athletic as Peppers. The entire appeal of Peppers is that he is huge, powerful, and athletic.
Yeah, I know. I'm just saying, let's say every team wants him. Which I'm sure they do. Then I would eliminate the ones who have two strong starters at OLB in a 3-4. Miami would be eliminated just from what you see on paper. So, I doubt they think it's worth giving up that much to bring in a guy just b/c of his size/athleticism combo, when they have two guys a bit smaller to give them the same production as he would.
That being said... I'll gladly take a few of their high draft picks and a player if they are dumb enough to do it.
