Unless something really crazy happens, Mayweather should put a nice solid beating on Berto. It might be an entertaining beating because Berto is going to try his best, but it will be a beating.
The odds reflect that.
Per @BovadaLV: Floyd Mayweather is a 100-1 favorite against Andre Berto.

You might as well put $20 on Berto who is +1600 underdog, just for the hell of it.
