This would be a WAR! Prime vs. Prime who takes this one in a 15 round fight? Lyle was one of the hardest punchers in the 70s, and he would hit harder than anyone Rocky ever faced. Lyle has the size (220lbs) and the strength required, to really hurt Marciano. Marciano has the higher workrate and he definitely has enough heart to go into a slugfest like this and come out victorious, but if Lyle can take all of Foreman's punches, can Marciano really knock Lyle out? With about 35lbs of weight difference, Marciano would have to work really hard to put Lyle on the canvas. Can Lyle beat the 2nd best Heavyweight of the 50s? Or can Marciano go through this tough top 10 contender from the 70s? I might go with Lyle by TKO, but I wouldn't count Marciano out in this one.
