Beyond his insane skill set I believe the thing I like to see when I watch him is the leadership by example. He is a beast but he also never gives up on a play, I don't know how many times this year people have been run down from behind by one of our D Lineman, but I notice it far more this year then in recent history.
The fact that he is such a beast physically is one thing but the fact that he NEVER STOPS is far more impressive in my eyes cause that is about character not just ability.
When I look @ what Pelini defenses have done for DLineman recently (Glenn Dorsey @ LSU and now Suh) I think we are in good hands once Suh starts playing on Sundays, but god I am gonna miss him.
