Floyd is 35, what you want to wait until he's 40 so they have a chance at beating floyd? fukk outta here
Khan is as ready for Floyd as he's going to be, and he wants to fight Floyd. To me, that's the best fight to make assuming Pac's not going to fight him. Alvarez isn't ready but I really can't see him improving to the point of being ready for him; that Paul Williams fight could have been a great chance for him to show improvements and prove my thoughts wrong.
I assume Floyd's not going to fight again this year, so I would love to see Khan-Bradley fight but I highly doubt it. Khan's the only guy I see being even a worthwhile opponent for Mayweather this year (outside of Pac); I don't even think I'd watch Bradley-Mayweather if I was paid to watch it, not that it'd be an option.
