In hindsight after Hatton ,I bet Mayweather secretly regretted stepping right over 140 when Kostya was there for the taking. That fight would have changed his and boxing history one way or the other.
I give him full props since though,he has faced alot and turned me around in my original thoughts about his style and if he could handle a war.
I dont doubt him anymore, he is the best. If he wants to up the anti and prove it once and for all just Margarrito would seal it.
