at 154 theres a few there that could give FMJ trouble with the natural size advantages. at 147 probably only PAC could give him trouble, a 100% amir khan could also give him trouble, though whether he can perform at that level for 12 rounds is unlikely. Floyd will go into any fight below 154 as heavy favourite
In his current state, several guys give him loads of problems with potential for upset, but no one I would say for certain beat him. Bradley, Lara, Andrade, Trout, Pac, Khan would be the top guys that come to mind.
Maidana already beat Floyd with pillow gloves. In the past Castillo also did it. Pacquiao will also beat Floyd.
Only a moron calls 8oz gloves pillows. They don't tickle. It was a b*tch move by Floyd but Maidana didn't have the ***** to make a stand, so he was all talk. He even said no rematch without his gloves but his b*tch a$$ got back in the ring without them
No man is unbeatable. Only when the man chooses to avoid the best contender for years out of fear, then maybe he is.
