Stevenson was a great fighter, tall, angular smart, rangy, snapping straight accurate punches, KO power. In 1976 after he KOed John Tate at the Olympics George Foreman said to Howard Cosell on national TV there was no doubt he could be world champion as a pro. You're not gonna get a better endorsement than that. I believe Stevenson was one of the all time great heavyweights. In 1976 he could have beat Ali, Frazier, Norton, Foreman and anyone, he was that good.
