McCallum used his jab to good effect in the rematch. I think we have to allow for the fact that he could have had an off-night the first time around. But Kalamabay's jab was certainly one of the best MW jabs. Also like Marvin's a lot, but the way Sumbu floated in with his jab much like a prime Ali is a beauty to watch. He also liked to double and triple it and jab to the body. Flawless, really.
