He's aged man, plain and simple. I don't see how anybody can't see the slip. He's still great, but the man is pushing 36. That is very old in boxing. He was taking some rounds off in that Cotto fight, and round 8 was the worst I've seen Mayweather lose a round in like 10+ years.... It's only a matter of time. People thinking Guerrero will be a walk in the park may be surprised. It could be, but Floyd could get old over night and be in for a war. It has happened to many greats before him. The Mayweather of old is long gone. To me, Ricky Hatton was the last fight I consider his prime. It has been a slow decline since with aging and inactivity.
