A bit of a stretch, but what about World Middleweight Champ Marvelous Marvin Hagler fighting The World Light Heavyweight Champion, Michael The Jinx Spinks, in 1984 at 170lbs?

Another stretch, and indeed they would meet, but what if Holmes gets the nod over Spinks in their rematch, and then fights the then unproven Tyson in late 86 (instead of Berbick/Tyson)?

Duran's finale at Lightweight being against Arguello.....

An 1981 match up of Pedroza and Sanchez.

The same year seeing further unification at 118 (Chandler/Pintor).

I fear it may of been a bit one sided, but it would of been interesting to see Micheal Second too (many) Nunn fighting Nigel Benn in 88/89.

I know they were great mates and stuck to their principles, but Norton/Frazier in 73/74 would of been fun, if both gave their best.

Again they would meet, but what if Holyfield instead of fighting Bowe, fights a then not totally proven Lennox in late 1992?

Leonard decided he does not the easy tune up and fights Hearns at 154 instead of Howard in 84.....

Whitaker gets the nod over Ramirez in France, and he gets to fight the great JC Superstar in his 135lbs prime....
