Sumbu wouldnt get caught as he did against Nunn, imo He expected a long drawn out fight with plenty of slick moves, Nunn caught him with a totally unexpected shot from the blue. It probably wouldn't happen again in a 100 fight. So he'd be prepared for McClellan, he'd know how Gerald was going to come out for a war. So I reckon we'd see Sumbu at his best, not giving him anything and pacing himself. By the 9 th we'd see Gerald totally blowing, Kalambay would win every round going from there on. Kalambay by decision.
I think the Nunn knockout was a one in a million shot - one of the great knockouts but one of the most surprising too. I don't think lightening strikes twice here. Kalambay would be on hyper alert in the early rounds in a way he probably wasn't against Nunn. I expect the Kalambay who outslicked McCallum to do the same thing to McClellan. Clear points win for Sumbu.
