didnt tyson look like a complete slob last time he weighed in? and didnt he bite of an ear to avoid being defeated?
boxers are incredibly tactical fighters, but they have spent their lives training to the rules of boxing. UFC fighters have trained in many different aspects of fighting, and by the look of tyson last time i saw him, maintain a higher standard of physical training than him. yet for some reason when you are putting tyson in an unexplored medium for him you seem to think he would definately win because the guy is a psychopath.
how much all round fighting experience do you KNOW tyson has? how many do we know UFC fighters to have? thats why i think he wouldnt win, we know"UFC guys can kick, grapple, punch, lock etc. we only know tysons ability to punch and bite
as for tyson being able to land a punch ultra quick and instantly end the fight, why is it that doesnt happen in every first round of every boxing match he has ever fought? what makes people assume it would happen against a UFC fighter
