This is one of the best matchups of the last few months, and no doubt the real main event of Showtime's card next week. Rafa Marquez is one of the hardest punchers p4p today, and also a pretty decent boxer. His defense has some holes and he has also shown some vulnerability chin-wise in the past. Mabuza is a sweet boxer-puncher who throws fast and accurate combinations. However, I don't think he's slick enough to stay away from Marquez's power all night long. Cruz Carbajal, a much rawer guy than Marquez, was able to hit Mabuza more or less consistently when they fought for the number one spot a few months ago. Soooo, in my opinion, the key to the fight will be who can better take punches from the other guy, because they will hit each other (make no mistake about it!) Given the power factor, what I will be looking for as the key is how Mabuza reacts the first time Marquez hits him with a serious shot. In sum, a great little matchup that has received little to no attention by the heavyweight obsessed media. What's your take?
