Although I get your point, I don't think it's fair to compare Suh to Haynesworth. Haynesworth never had 5+ sacks until he was playing for $$$. Haynesworth is was a useless sack of crap that wasted his talent. Suh busts his arse every snap.
Suh is known to take plays off. I would say Haynesworth and Suh have the same attitude. Head Stomp/Road Rage.
Unless those "plays off" are run plays (which I should have qualified) I haven't heard that criticism. I've said since day that he doesn't play the run well, which got a lot of backlash around these parts, but the guy goes after the QB. Haynesworth didn't give two craps until it was time to get his big payday - something I also said that got quite a bit of backlash around these parts.
