Thats who this falls on, the refs in MMA are so timid with the rules its not even funny.
-Low blows? 1-2 fouls usually get a free pass, no problem.
-Eye pokes? Same as low blows, 1-2 fouls get a free pass, no problem.
-Knees/kicks to the head of a grounded opponent? Unless they are very blatant they get called accidental and move from there to DQ/NC/Point.
-Blows to the back of the head? Almost like a recommendation than a rule to them.
-Cage grab? Not a big issue for them, they just warn the fighter to stop doing it, at best.
-Glove grabbing? Not a big issue for them, they just warn the fighter to stop doing it, at best.
I would say the first two need to be addressed and up the punishment to 1 point on all of them no matter what.
