The most technical, diverse, and action packed sport on this planet.
Apart from the freakshows like Kimbo, Jose Canseco, Hong Man Choi, & Herschel Walker, these are the most supreme athletes on this planet. I understand how some may think its barbaric and not a real sport, the champs just show the skill and mental game needed to fight. From Wrestling, BJJ, Judo to Boxing KB Muay Thai, the show never ends.
You can tune in and watch a guy get clipped with a left hook right straight combo, see a guy get slammed on the canvas, or watch a guy being tied into a knot, its all there.
