Anaclet Wamba
Carlos De Leon
Juan Carlos Gomez
Marcelo Fabian Dominguez
Thomas Hearns

I don't know who Wamba is, to be quite honest. I'm either forgetting or just never heard of him.

As to the others, I think he beats De Leon and Dominguez soundly, quite possibly by stoppage.

Hearns isn't really fair, because now we are way out of his best range, in age and weight. Haye probably stops him too or wins a lopsided decision.

Gomez probably beats Haye by decision, though I think it would be a cracker.

Gomez or Wamba are probably the best cruisers in the list. I'd say both outpoint Haye. At a push Haye stops the rest in the mid-rounds.

Wamba UD 12 Haye
Gomez UD 12 Haye
Haye UD 12 Dominguez
Haye TKO 9 De Leon
Haye TKO 6 Hearns
