I'm of both mindsets. I would definitely watch and enjoy it, but at the same time I'm not sure it's necessary.

I think that their previous fights have defined their careers and taken their toll on both fighters, so why throw them back into the mix? Let's see another epic!

Although... I do want to see them face other fighters and as I just said, those types of fights take tolls on their bodies and make it unrealistic that they ever fight anyone else. I would watch either of them face other top tier competition too.

Tough decision.
