One thing to consider is the weight of the gloves. Back in the days they did fight with lighter gloves then nowadays. So what is going to happen when Lewis is wearing the small gloves Louis and Marciano used? Might be pretty nasty. And what is going to happen when Louis and Marciano wear todays bigger gloves. Will there punches have the same impact? I think not.
Lummox Lewis takes this one. Marciano has to pull a Jermain Taylor and does not finish the tournament.
