The sensible thing is now Cotto, because that's where the money is. Easily PPV money. May not be $50 or $60 bucks, but it can get a few people between $20 or $30 buck PPV bracket.

GGG and Quillin on PPV can happen as well- but certainly no more than $25 bucks for the show.

I'd say, and not necessarily in this order:

Cotto; Quillin; and then Ward.

The fight with Quillin has to happen. More than the other fights. The unification fight with Quillin just has to happen.
