I believe this is the link you requested on all fighters history. Jackson johnson would beat all of the champion heavyweights. Peace.233189866422

You think Johnson beats every Heavyweight champion there's ever been?

Erm, nah. He doesn't come close.

Jack johnson was "the greatest" no doubt!

Emphatically! He'd Ko Joe Louis within two rounds, Ali he'd catch up to in the 8th - 10th round. He was a Master Boxer/Fighter. He'd paw with them and knock them out.
