Floyd Patterson (Bonavena fight) vs Joe Louis (any version Ezzard Charles fight or after) whichever version of Louis you think was the best from that point onwards. Who wins this matchup?
Patterson points win, way too fast for Louis who won't even be able to react properly to Patterson's offense. It will be interesting to see if the jab and inside skills can slow Patterson down but by then, he will be well ahead on the cards.
