Do you think he can fight on for? I'd say another two years at WW (hope he doesn't fight @ 154 again).
2 years and 3-4 fights. Hope Manny accepts a career high payday and fights Floyd. I think Floyd will challenge for a 160 title eventually. Probably take the fight at 155-156 like Oscar did with Hopkins.
Floyd will likely have two more fights at best - more likely one. I can't see him sticking around for 3 or 4. Pacquiao will never happen. That ship sailed. Once Khan beats Peterson they'll rev-up the ridiculous hype train for Floyd v Khan (which will be a decimation and schooling).
While he may be showing his age, not many fighters on this planet could do what Cotto did. Them body shots made Floyd stay on the ropes, Cotto is one of the best at that.
