Quartey by decision. Starling had a great defense ( the original Winky Wright defense) but I feel he'll be outworked by quartey's jab jab jab. Evenly matched affair but quartey gets the decision
Probably come down to the end of the fight, as both guys feint the shit out of each other for most of the fight. Probably not a fan friendly bout. Starling had better stamina so I think he pulls out the decision in the Championship rounds, after clowning around with Quartey for the first 10 rounds or so.
Quartey would be busier against Starling than against a speedy guy like DLH or a hitter like Lopez. I don't see him posing that much with Starling. I think he'd take a close clear decision.
