Lewis would have a very good chance of running onto a bomb from a taller, faster and more powerful champion opponent. What proportion of Lewis's non-bum opponents got taken out in a round or two? How good was their durability/heart/power? How many times has Wilder been taken out in a round or two? It's ironic because Lewis was, by a guy who was a relative non-puncher. I know people like to say silly things about hypothetical matchups but Wilder is no more Michael Grant than Lewis is Gerald Washington.
