A.Silva - TDD
Shields - Sub Defense
Sherk - Arm length (hard to be a striker with the shortest arms in the UFC)
Carwin - Gas tank and/or patience
Fitch - Finishing (from a huge Fitch fan)
Silva has pretty good TDD actually. Sonnen takes everyone down. And also he was probably hurt.
Shields has bad sub defence? how do you figure that...hes never ben subbed and is actually a submission specialist :S did you mean Sonnen?
