I used to not like BJ, but if you watch his fights against Matt Hughes, and GSP, you can see that he's really as good or better than both of them, plus I thought he was funny on TUF, so now I'm a fan of his.
Back to his fights w/GSP, and Hughes. He dominated Hughes in the first two round before Hughes pummeled him, which he was able to do, because BJ busted a rib in round 2. Everyone says he gassed, but he said he broke his rib, and he had an MRI later that confirmed it. In the GSP fight he whooped GSP in round 1, and then lost a close decision. I was cheering for GSP at the time, but I was still surprised that he got the decision. It was really close.
