Tyson...his punches had every bit of anger in his life on them as if the opponent did something to his mother.....when he misses it looks like it hurts.
Tyson by canabalism. '86-'88 Tyson is just too much for The Rock. Decisively better at everything except conditioning.
Tyson 95%+ of the time at the very least. In a street fight, Rocky would have a half decent shot because Tyson looked at people leery when he sees them in the street, but in the ring he's supremely confident.
i reckon 50-50, if they fight 10 times, they'll win 5 each. at the end of the day, if prime tyson catches you, he wins the fight. marciano would walk through it half the time, and the other half he would crumple.
