I've been thinking about this mayweather retirement and I'm betting as soon as DLH announces his next fght, Floyd will as well soon after.
I think DLH blew hs chance wth his medocre performance against Forbes. I think that fight was supposed to generate interest in a rematch, I think GB probably thought DLH would blast through Forbes. Turns out he didn't and actually ate more punches than I've ever seen him eat before. Oscar struggles with a guy who was feather fisted at 130 at 150 who was admittedly picked because he was a lesser version of Floyd. Couple all that with the disappointing first fight...
I don't think Floyd wanted the oscar rematch. If Cotto beats Margarito in front of a large audience, convincingly, I think that fight happens. Otherwise, the retirement may be real as there is no big fight out there for mayweather.
