How was he "barely" 80%? He was in training for a fight, both Vitali and Lennox had equal amounts of prep for each other, Lewis got the win in one of his more exciting fights then bottled the rematch, the rest is history.
he was 37. thats all that needed, and you know it. Question is why you are avoiding bringing the obvious up. Let us know why, at some point in the future. in the same way one cant bottle it if you ripped someone to shreds first time. 2 denials in one post makes for a weak counter.
frotunately people dont retire anywhere anytime, they retire, ALLL THER HW CHAMPS did, by 38. so he did wat was norm, but you want to interpret the norm as different in this ONE SINGLE CASE out of all 40 or so cases in HW history becos your hero got killed so easy.
