I voted other.
What I mean by that... Mosley could have given him a very good fight in his prime, but he's not in his prime anymore.
Hatton, Margarito, Cotto.... they just don't have the speed. Floyd outboxes all of them.

I actually think that Paul Williams has the body type to bother Floyd with his height and reach (similar to Forrest against Mosley) but Williams is way too raw at this point.
