What heavyweights of the past 50 years could Jack Dempsey NOT beat?

[Mr140]

Well he would not even fight most of the Heavyweights because they were black for one thing and he woud not get in the ring with him. I think he gets his ass handed to him by most heavyweights form the 40s on word. He was great for his time but he was not even the top dog then because he ducked the best guys and when he fought one of them got owned. I mean Tunney was a great fighter but he was not even a heavyweight really and boxed jacks ears off to the point of making him look like a bum.
