Ultimate Showdown

[T.J. Combo]

These questions of who would win in a fight between big guys and guys with training made me think. When the big guys have training who's the best?

So if a time machine were used to bring together some of the greatest fighters in their prime, who would come out on top?

Details of the fight: Anything goes whirlwind match in the octagon, a fighter is eliminated by knockout or submission. There can be only one.
