Mustafa was a bit too easy to hit for my liking to see him have any real success against a banger and precision puncher like Julian. Mustafa may ring his bell once or twice, but my guess is that he gets laid out for the count at some point unless he plays it safe and takes no chances en route to a points loss.
Jackson was one special puncher, and I think he'd eventually get one in on Hamsho, and then the birdies would sing.
Hamsho's chin in his prime would take the dents, and he would wear down Jackson to take an eleventh round decision.
