I think Dida needs to either work on his ground game or his TDD because I don't think anyone at 155 can stand with him. He rocked Alvarez pretty hard and Alvarez is a big dude. But for the second fight in a row he got destroyed on the ground and he really needs to figure something out because he is so good standing.
If these are really the brackets then it's going to be Kawajiri, Ishida, JZ, and Hansen in the Semi's which is a pretty good group.
Also another note from the show Dida's Punisher's UDL shorts were sick looking.
