I'd love to see one person take Tyson down to the ground after getting fed a jab/cross from him with 4oz. MMA gloves... he'd knock anyone that tried into next week... some of you guys are delusional in his prime there isn't a person in the world that could fuck with Tyson. Remember to take him down you have to get close and shoot in, that leaves your chin very VERY open to get KTFO.
wow... just... wow...
Have you even even done mma or wrestling? Because this is about as far from the truth as could possible.
Try punching a guy shooting for your legs on the chin. It pretty much impossible because you'll hit the top of his head. BFD, that won't knock anyone out. Oh, and a shoot against someone like Tyson(or any pure boxer in general) would be initiated OUTSIDE punching or kicking range. So no luck knocking him out from that distance either. Fight tactics are used in boxing as well as mma, but boxers don't have a tactic to counter mma-fighters, while (smart) mma-fighters do have for stand-up purists.
If people still think in this age, after all mma has proven, that a stand-up style purist still has any chance to beat modern mma-athletes other than what we in mma call "boxers chance", they are either complete imbecils or fanatic fanboys. There have been quite a few world class striker-purists that have been submitted without even the possibility to throw a single punch or kick.
Search for Ramon Dekkers only mma-fight(which was in pride or k1-heroes I think, ufc doesn't equal mma), a living legend in muay thai, probably the best p4p-thai fighter alive, but in mma the guy got completely toyed with and humiliated.
"What if they developped world class takedown defense".
Yeah, because that happens over night and completely doesn't need years of hard training and serious natural talent. What if I developped world class takedown defense, submissions and striking game... Why, I'd win every fight I'd enter! I found the holy grail of mma!
Unfortunatly it doesn't work that way.
The only way tyson would be a favourite in an mma fight would be when he fought a stand-up guy with very little offensive ground-game, like Tim Sylvia.
