There's no hype about Bute, whatever you hear about him is because he shows great talent. He's not an incredible athlete but a good one with a very good set of natural skills and overall technique. Taylor wouldn't be able to land as easily against Bute than he did versus Pavlik in both fights. Bute moves his head much more and has a way better defence. The only thing is..he normally throws half of Pavlik's natural punch output per rounds ! To try and beat Bute, Taylor would most likely have to win the fight at close range which is different than what he needed to do with pavlik.....
