I gotta agree that this is a nightmare fight for Joe Louis. I don't see how he wins this against a prime Ali. Ali would outbox him with his superior speed, but unlike Conn, Ali will be able to hurt Louis. I see Ali stopped Louis in the later rounds.

I would be more interested in seeing Louis vs Foreman, Frazier, or Marciano (a PRIME Louis, not the old shell of Louis that fought the Rock)
