that is the problem with fighters, must of them retire when they know they can't compete anymore at the same level. I do understand Marquez can milk a couple of millions with a win like that in his next fight, and he clearly can still fight at least 2 more fights. but who is out there? He can milk millions with a rematch with Pacquiao, but high risk to lose. Floyd is a guaranteed UD lost. The rest are not going to give him the quantity that he can milk out of this win. dude is 40 with over 60 fights. I say he should really consider leaving with a devastating KO win over his "nemesis". Recent example was Cotto. He fought really good against Margarito and beat him in a very satisfying fashion. what happens next? he decides to fight Floyd, no shame there to challenge the best. Now he lost to him, then fight so new up and comer champ and lost very bad and looking awful at it. now he is saying he wants to retire after losing two times in a row. He did retire at least 20millions richer in those 2 fights, but he was considering retirement after the death of his dad, what kept him to not retire was that margarito lost, he avenged it, that would be perfect picture retirement.
