The key here is to not use revisionist history, before the Mosley fight nobody knew or even thought to ask if Margarito had loaded his gloves. He had just beaten Miguel Cotto who was undefeated and looking for a shot at Floyd just as much as anyone else at 147 in that time period.

Floyd IS a great fighter, but there are questions about why he chose to fight who he did when he did and at the weight class he did. And those questions are there for ANY fighter but more especially one that considerers themselves great.

Ricky Hatton after his debacle of a performance vs Collazo at 147 showed he couldn't handle the weight

JMM after extremely tough fights with Juan Diaz and Joel Casamayor at 135 and Floyd still decided to fight him at 142

Those make me question him...prudent moves, but they allow for "what if's" to be asked. What if he fights Hatton at 140? JMM at 142 is erroneous because Floyd couldn't make 135 again and if he did he'd either keel over and die from the weight loss or just massacre JMM.
