What do these fights have in common?

[IamInuit]

Where they all upsets on paper? Hard to believe a few of them would've been, but I can't think of any other possible tie.

Some were I suppose but not the answer.

Hmmm.... My first guess was going to be all for lineal titles, that isn't it either though I imagine?

No but thats another cool answer

[Primo Carnera]

Were they all unification fights?

Were they all unification fights?

Nope but another good answer.

I spent too much time trying to guess on this one but all I could come up with is they all were refereed by a man who had at least one vowel in his name and they all were wearing gloves at the time. Did I guess right?

Lol no cigar.

I don't think that I could venture a proper guess but as far as I can see all the participants fought the best people around at the time and most of them fought their opponent in his prime. If I may say so the guys that fought the champs in your list were the cream of the crop. Guess I blew my bolt but I will keep trying to guess the answer.
