Your right there is some very tough bodyguards out there.They are very quiet and reserved, but they would clean Brock Lesnars clock.Alot of them are highly trained in self defense, and could easily dis-arm a man with a gun in seconds.
Just because some one isnt in the lime light or well known doesnt mean they arent a badass.Most of the guys I know who are really bad, and are really crazy, are very reserved people.But if you fu#$# them they would tear your head off.
Besides bodyguards there are alot of guys who own hard core fighting gyms who just love the art of fighting.But you wont see them in the UFC.They own hole in the wall gyms, that look like dumps, but some of the best fighters come out of there.
Johnny Taco gym in Las Vegas, was a dump, but alot of the best boxers in the world trainined there.Mike Tyson in his prime trainined at that gym on a regular basis.
Sevaste some of the toughest, and meanest people, are nobodys to the general public.But they would kill most of the guys in the UFC.The UFC has some talen, but they arent the best fighters in the world.They are just the best marketed fighters in the world.I have seen street fighters who could beat alot of the guys in the UFC.
The UFC, did something amazing, they brought fighting to the general public, because people were bored with boxing.
The UFC is all marketing , they only care about the bottom line $$$$$.
