I edited the first post to make the fights vs Tyson, Holyfield, Bowe, Lewis and the Klitschko's 12 rounders.
I suspect that Jack Dempsey would be more sucesful against the larger heavyweights (and hence a wider spectrum of heavyweights) because he has the key equalizer e.g. finishing prowess.
Well, I guess I'd better start answering my own question, at least for a few of the match-ups.
