I've thought about this enough to get a headache and then give up. What about all the non-marque fights that were great but didn't have the notoriety. There's just too many of them.
So instead I'll modify your list
Replace Hagler vs. Hearns...because it was too short, with Hagler vs. Mugabi.
Replace Tyson vs. Douglas...Because it was one sided, with Bobby Chacon vs. Boza Edwards II....I think they fought twice?
Can't argue with the others.
BTW. Worst fight I ever saw.....Holmes vs. Tex Cobb, the fight that literally retired Howard Cossell.

He was so disgusted by it. LOL
