Sugar Ray Robinson V Archie Moore - there was talks of this happening instead of the SRR V Maxim fight, had Robinson had won this would probably have happened.
Rocky Marciano V Floyd Patterson - Marciano considered coming out of retirement as he was unimpressed with Patterson and fancied himself to beat him. I think the loss to Ingemar ended any fancies of making a return.
Any others
