Greatest Hw below 6 feet

i go tyson definetly with marcean a close second

The fact that Tyson is really around 5'9-5'10 makes him the best because of the great size difference.

I can't believe you guys pick a fighter who has lost every big match he was ever in over the only undefeated heavyweight champion in boxing history with the highest KO% of any heavyweight champion in history. Under 6' is Marciano without even anyone on the same radar... over 6' would be Ali followed closely by Louis.

Under 6' would have to be Tyson. Over 6' would either be Lennox Lewis or Holmes.

Tyson with out a doubt

I pick Tyson but I think Marciano could beat Tyson. I only pick Tyson because I think Tyson at his best would have a better chance against the great big heavyweights then Marciano would.
