This is idiotic.
He also came back and beat Norton and Frazier twice. He lost to Holmes when Holmes was in his prime but Ali was 38 freaking years old and shouldn't have even been allowed in a ring. How are you seriously using that loss against Ali?
You claiming Ali "only really fought a handful of good fighters" is like arguing an SEC team "only beat a handful of good teams" in football at the expense of reducing Alabama and LSU and bringing up Vanderbilt.
Ali's victories over Liston, Frazier, Norton, Foreman, Patterson(the first fight) are better than any wins Tyson had. At best Tyson's win over Spink sis comparable to the Ali-Patterson victory.
