Al, isn't all you are doing comparing similar fighters (style-wise) to each other?

That will probably tell us who is the best brawler, or pure boxer, or box-puncher etc - but wouldn't it be good to put (say) Marciano up against Jeff Willard, to see if he could do what Dempsey did, or whether Willard would have found a way past it?

You have a good list there, but a little jiggle around then gives us hours to thought and topics of conversation?

Hagler - Robinson at MW? Would the real Sugarman have conned Hagler the same way?
Hearns v Benn at middle?
Liston v Frazier - would Old Stoneface have ambushed Joe as quickly?
Holmes v Foreman - Larry couldn't rope-a-dope as well as Ali, but he would approached the fight in a different way?
