BJ Penn, Dan Hardy and Rashad Evans are fighters I used to loathe but now find myself rooting for.
I used to be a huge Rampage Jackson fan. I've met him and he's really nice and hilarious and always brought it in the cage. But lately I've been disappointed with his attitude regarding the sport. I wouldn't say I hate him or even dislike him, but his fight with Glover will be the first in a while that I've rooted against him.
I used to like Dominick Cruz until I found out what a jerk he is.
