Depends. Oscar said(before the Tito-Vargas fight), that he would never fight Vargas. I think he was scared. IMO, probably the same outcome. Vargas wouldn't have outboxed him, and would have came for the kill. Oscar don't hit as hard as Tito, but he still cracks, and would have exposed Vargas with his left hook. But, that's hind sight, and at the time, I might have bet on Vargas, who knows.
