He is very good, especially early on. When he cannot discourage his opponent though he seems to run out of ideas and retreat into himself somewhat. Maybe that's okay when he has banked early rounds, but you can see he isn't so devastating now that he has stepped up and bit by bit opponents are seeing more that they can work on. Guerrero is really inactive didn't have the ideal prep for a big fight and he has looked a bit off in his last few fights anyway. I detect a little bit of Jermaine Taylor in Thurman. I can see an opponent who can weather the early storm and take his punch cause him serious problems as he is taken deep. Or maybe Thurman will just get better and better, but it's more likely that a wall is hit. Maidana would answer a lot of questions and a Khan fight would be very fun, maybe Bradley too. He's too raw for a super fight at this stage and I want to see him taken deeper first.
