Holmes wasn't even within seeing distance of prime Bummy. Barely a shell of the fighter he once was, and don't forget he still beat Spinks in the rematch, regardless of impotent judging. We may as well look at the last two Walcott fights and Rex Layne as well for a comparison.
Yeah Bummy is the master of doing the fair comparison argument
If it was Ali he be comparing the Ali of the Young and Spinks fights against his 50s overated heroes - actually they were great but to light to compare against ATG heavies apart from the big hitters like Dempsey and Charles wasn't. Holmes beats Charles.
