Whitaker could fight inside when he had to, his holds were part of his style to do what he did best and that is frustrate. Whitaker was something else, and Mayweather is a gift, not like Pernell but a gift none the less. Pernell would have won every round from Margarito. I think it will be competitive only because unlike many great fighters Floyd cares how he looks in the ring when he's fighting, this will get him caught more then he needs to be.
