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

Jack was the shit for his time, but times change, technique improves and evolves, and obviously our athletes are a lot biggers, stronger and faster than they were 100 years ago.

I looked at a list of the world champs over the last 50 years (from Patterson on) and honestly I wouldn't pick Dempsey against any of them.

And I certainly have a hard time believing he'd do anything against our modern super-heavyweights. I know people will point out that Jess Willard was a legit SHW, but 1) Jess Willard was a bum and 2) he didn't have the explosive athletic ability combined with skill that a modern SHW has.

I agree, but not positive about Patterson.
The question should be about the cruiserweight division, in my opinion.
I don't really like this thread because no matter how you word a negative answer, it sounds like you are putting down Dempsey which is the last thing I want to do.
