The guy has a brutal rep. Here is a site listing his "dirtiest plays"
If Suh played in the 60s & 70s, he'd be all over NFL films & they'd be talking about how he was the grittiest & toughest of all time. Instead, he's a goon. Granted, he's done a few stupid things, but the guy just plays balls out all the time.
Analyzing those "dirtiest" plays:
HM. Trent Richardson - Suh dives to stop him from getting the 1st down. Richardson wasn't going out of bounds. Verdict: Not Guilty
9. Marion Barber hair tackle - 100% legal play. Verdict: Not Guilty
8. Andy Dalton - Dalton starts to run, Suh gets a hold of him as he throws, throws him to the ground...roughly, but not dirty. Verdict: Not Guilty
7. Jay Cutler forearm to back of head. Was a push to the upper back. Verdict: Not Guilty
6. Jay Cutler. Suh starts his tackle BEFORE Cutler starts his dive. Suh finishes his tackle & Cutler's helmet pops off because of the way his body stopped sliding. Verdict: Not Guilty
5. Jay Cutler III. Suh sackes Cutler from the side and lands on him hard. 100% clean. Verdict: Not Guilty
4. Jake Delhommer. Ouch. Verdict: Guilty as charged
3. John Sullivan. Suh is slightly in front of Sullivan as he blocks him from as close to the side as you can get. The fact that both were running diagonally, made the hit worse than it was. Verdict: Hung Jury
2. Schaub's nuts. As the lineman pulls Suh to the ground by his leg, Suh reaches out and gives Schaub a love tap to the vagina. His 2nd dirtiest play??? Gimme a break. Go watch women;s tennis. Veridct: Not Guilty.
1. The Stomp. After Dietrich-Smith did absolutely nothing at all to provoke him Suh stomps on him after getting up from the pile. 100% bush league regardless. Verdict: Guilty
So out of those 10 plays, Suh broke the rules 2 times. That's it. Twice. The rest are all borderline at best, most of them within the legal rules of the game. That's what happens when the media & sheepish, butthurt, homer fans get involved.
Suh is a monster. In a very good way. Here's hoping that he enjoys a nice long career as a Detroit Lion on his way to the HOF.
