Makhmudov is going to need to go thru some known second tier names to make anything like this happen. Just can't see any risk/reward equation that makes it viable for Ruiz. Hard to make a vote until pro Mak. version has had his chin tested and gone closer to 10 rounds, only Rice has taken him over 3.
Actually Ruiz might be Tailor Made for Mak. I would pick him by upset KO win.. if it wasn't for his glass body, so Ruiz probably
