First one sold 1.4-1.5?? Only way this one sells less is if the masses are really pissed off with Floyd ducking Pacquiao....
First one's numbers is an upper bound. Take into account the obviously dissipating interest in Mayweather's fights..plus the fact he already beat cotto? Not buying it. Plus, Floyd's numbers have always been inflated in comparisons when he fights on may 5 (and the others don't). Alvarez/cotto is a bigger fight if you ask me, a Puerto Rican or a mexican.
