Tyson. Norton lacking the footwork here. Norton was also a guy who could get psyched out. I actually think that was a bigger chink in his armor as opposed to his chin.
It's become a cliche that Kenny struggled mightily with sluggers but clichés contain kernels of truth. It's hard to not see Kenny being overwhelmed.
either Tyson will win very quickly or lose at the end... probably a lot depends on your attitude. but in no fight after prison I saw Mike ready for someone like Norton, although the combination of styles favors Tyson.
