It depends, if Haye could box for the entire fight and not try to knock Holyfield out he has a chance, however Holyfield would always get to him and had a deadly left hook, Holyfield would take Haye's shots and probably wear him down late, if not stop him.

But, if we wanna talk about a Cruiserweight toss up fight. Michael Moorer vs David Haye would have been a barn burner! For as long as it lasted.
