How you look means NOTHING in the UFC, except maybe that you get or don't get respect.
Look @ tim Sylvia, that man hits are as hell...
THat said, Joe riggs is much more muscular than Diego. Forget about lighting. The weigh in was identical lighting conditions and it really brought out the difference. The pictures someone else showed were good lighting for diego and bad lighting for riggs.
My Top 5
1. Cro Cop
3. Mauricio RuA
4. Quinton Jackson
5. BJ Penn
