I think Quartey would be able to frustrate and discourage Mosley for good portions of the fight with jabs and heavy right hands, and survive a late rally from Shane and win a decision.
My feeling on this matchup has always been that Ike would be in control through 8 rounds, but given his dodgy stamina, Shane might pull it out late, and probably score a late KD of Ike that ekes out a decision for him.
