Yes Frazier over Ali is incredible but Frazier was a heavyweight, Conn was a light-heavyweight coming up weighing in at 168 lbs to beat a man who is usually regarded among the top 2 greatest heavyweights off all time. I think it would top Duran -Leonard because although Duran moved up divisions the weight differential wasn't anywhere near Louis-Conn, it would literally have been David defeating Goliath.
