I think everyone knows I'm a Lions fan, and when I saw that play live, I thought Rogers was being a bag, but after seeing the replay several times, I really can't say anything in Suh's defense.
He knew he was pushed into Rogers, and it was clear that he knew that he stepped on someone as indicated by his partial trip and attempt to regain his balance (which was incidental), but the second step coupled with him not willing to even look down made it clear that he was doing it on purpose.
Heck, he even ignored Rogers' retaliation, which he also was aware of.
If the Lions wonder why they're losers, can't win big games, and will never get the benefit of the doubt from the refs, look no further than your star players like Suh and Raiola.
If Suh isn't suspended, he'll have a target on his back and will be watched like a hawk in Dallas next week. Even a border-line clean hit on Romo will be flagged as a personal foul.
He's done it to himself.
