Whether its weight drain, personal problems, guys who broke their hands seemingly whenever they weren't dominant, what excuses do you think were totally legit or at least more so than other ones?

I'm not really sure I bought into MAB's problems making a huge difference in the first Pac fight. Some do obviously. I do think Roy screwed his body up a bit going up to heavyweight and then coming back down for his fights with Tarver. Weight drain didn't help Toney versus Jones but I don't think it was a deciding factor. I'm not even a big Margarito fan at all but I have always been annoyed by the claim that Clottey would have dominated him if he hadn't "broken" his hand.

There are a lot of other ones obviously. Which seem to be the most believable to you and which seem like BS?
