Haha. Seems like the thread is kind of rhetorical to me, I doubt anyone believes there arent at the very least a dozen or so guys who would have clobbered everyone Marciani fought. It's not really worth listing Ali Holyfield, Lewis, Holmes etc. Im of the opinion that Marciano wouldve also gotten creamed against many HW's to precede him. It wouldve been more interesting to ask for a lst of guys who werent really considered great. I personally think even a few contenders or alphabet strap holders from the 80's and 90s wouldve beaten Marciano and anyone hje fought( Tony Tucker, Tim Witherspoon, Golota, Michael Moorer(could easily get Koed though) Razor Ruddock, etc.) I think Marciano was at best on that level in actuality, you put him in with someone like Lennox and its an epic mismatch.
