At this point, Floyd's only going to take on the most overhyped fighter for maximum dollars. Some crowd-pleasing brawler with no jab and defensive lapses. Floyd's too crafty a boxing scout to accept some A-level fighter at the top of their game.
As a boxer who relies on reflexes, he will have about 2 years left max. Since Hatton, he has been hit more and has lost that aura of invincibility he once had. But one could also say that is because he has been more offensive lately than usual.
