I think Ferrell is going to be a better pass rusher than Clowney has been in his career. Dude has never broken 10 sacks, but again, IMO he's in the wrong system. Kid's a 1-trick pony and he'd be great at it if they'd make him a down lineman and let him go after the QB.
Like I said, I'd be buying Clowney expecting much greater things out of him playing in the right system.
BTW, I was looking at Key a couple days ago. Motherfucker weighs 236 lbs!! How the fuck does this kid ever expect to get to the QB at that kind of weight?? He needs another 30 fucking pounds on him!
That's one of the main reasons I want Clowney, because Key needs to be a rotational guy until he can grow up and become a man.
