Do people really believe that Mayweather is retiring Sep 2015?

Its funny to read the Floyd won't add anything to his legacy from her on out, like he didn't have a big year last year. He won his 3rd FOTY award, only guy to do so in 3 different decades, and won a RING title in his 4th weight class. Now sure, Khan is a bad fight, but who's to say the other three won't be good?

Prior to Khan possibly and after Marquez, which doesn't look so bad after Pac-JMM 3 and 4, he'd fought all real good, good, or solud fights. Mosley, Ortiz, Cotto, Guerrero, Canelo.
