If Norton could hurt Ali with the right hand and Frazier could drop him, perhaps Louis could KO Ali. Ali was one of the greats but his personality has outgrown his undisputedly great acheivements. Not all the boxers that troubled Ali were all time greats and none of them were in Louis's league.

When Louis hurt someone they never got away. I don't think anyone who'se not got Italian blood rates Marciano up there with Ali or Louis.
