My guess is at worst, they will be the same. But the chances are they will be more expensive as this fight is a lot bigger.
I can't even fathom the turnout for this fight. The Mayweather-Guererro fight was big fight obviosly because it's Floyd but I wasn't expecting the weigh-in to be as rammed packed as it was. Hell, the MGM did an open training session thing for every fighter on the card apart from the main event so Mares, De Leon, Rosado, Love, Santa Cruz etc did a bit of pads in the on show ring in the lobby and the turn out was insane. That's the magnitude of these fights.
Met so many people out there, met everyone on the card expect Floyd and Guererro, Broner, Hearns, Roger Mayweather, Floyd Sr, Trout, Rafael Garica, Richard Schaefer, and many more. All just hanging around the MGM.
