Jaz,
First, is Floyd ranked higher on your ATG list than Manny at this point in time? And would a win over Floyd for Manny mean more to you than a win for Floyd over Manny in terms of legacy and ATG status?
Second, regardless of whether Floyd "What Have You Done For Me Lately?" Mayweather ducked Margarito, Mosley, Cotto, or Williams, or just chose not to fight them for whatever reason, we can both agree that he hasn't fought them and as such, at welterweight, he really hasn't done much. When he retires, because it is too soon to pass judgment, if he still hasn't fought any of those names, it should be taken into account when considering his ATG status.
