That's a tough one, one is a retread, the other is a fresh face-off. Both though will be good-to-great fights
I guess honestly its all about the undercards. Top Rank will be forced to put on a badass undercard. Although Rios/Alvarado II isn't enough of an attraction for me. And on Mayweather's front, putting Broner by chance isn't enough, unless he travels up to 140.
Idk, as long as I don't see someone like Ponce De Leon
