I would have loved to seen this fight. Don't think their primes coincided but Carr in his prime was beautiful to watch. I see Carr getting off to a fast start where Margarito, the grinder, would be putting the hurt on Oba late in the fight. But i see Carr hanging on for a close but clear decision in a very entertaining fight.
I agree with the others that Carr could possibly outbox him but more than likely he would not have the power to keep Margarito off of him as i see a late round stoppage or a bloody decision win for margarito
