The talent level in mma is very low. It has potential but some of the guys at the top level are laughable.
Boxing and striking in general is more interesting to watch than two guys rolling around on the floor.
Recent example.
World title fight, with one guy Carwin who gasses after throwing about fifty punches, comes forward in straight lines, zero headmovement, zero footwork, no Muay thai, slow as mollases, just boxing that a two week novice would know. Against Lesnar, a guy that gets hit once with an overextended uppercut and turns round and spends the rest of the round curled up on the floor. He has zero boxing or Muay thai. So much for well rounded. Two wrestlers, only one of them throws a one two.
