Not if Alvarez is fighting Floyd himself.
Cotto can't deal with real 154 lbs fighters and isnt comfortable making 147. He's a Canelo beatdown waiting to happen. I'd be amused if GBP tries to sell that fight separately at this point. If he'd beaten Trout, it's different.
What Floyd wants, Floyd gets. If they want Canelo-Cotto separate, it's not May 4th.
