People who you think would have been good at mma..

Perhaps because of some trait, for instance David Goggins became a Navy Seal than ran crazy triathlons where he was injured bad and kept going, who knows if he would have been if he trained mma but he sure has mental toughness, certainly a trait that would have at least allowed to to take punishment and not quit.

So any athletes, actors, or other big name people you think could have made it in mma?
