Who wins these stupid MMA vs Boxer fights?

In your honest opinion what would've happened if these guys fought at their peak in a UFC cage with UFC rules over 3 rounds? Could any great boxer have a chance against an elite MMA fighter?

1. Fedor Emelianenko vs Muhammad Ali
2. Brock Lesnar vs Mike Tyson
3. Anderson Silva vs Roy Jones Jr
4. Jose Aldo vs Floyd Mayweather Jr
5. GSP vs Bernard Hopkins

All won by the MMA fighters if MMA rules

Roy Jones Jr would have the best shot .. because i think Spider would be the only one to try and stand

Do you think they'd be close though or massacres?

In the cage I'd maybe give a miniscule chance to Bernard Hopkins.

I agree with LA and GolbeZ. I could see Spider trying to stand with RJJ.

Tyson would have the best chance IMO

tyson is his prime would of ko'd brock before he could blink.

Brock would take him down in less than 5sec and GnP him to death.

Tyson would have an extreme speed advantage. He would have the best chance of anyone listed except maybe RJJ because Spider likes to stand. But GSP has some of the best takedowns in MMA so B-Hop would be taken down whenever GSP wanted to.

Prime tyson weighed under 220 lbs, he's just not beating Brock(outside of landing a ko shot in that 5 second window, which is possible I guess). I think Fedor vs Tyson would be a more compelling matchup.

Toney has a shot of making these types of discussion's more compelling. And I don't think it's out of the question that he lands one on Randy.
