Sports have a goal besides caving a person’s skull in. I’m a big sports guy. Played them all. MMA is brutal and in any other situation it is called assault. Seems to me the idea is to take your opponent to the brink of death, then you’re “the winner.”
I’m not saying it should be illegal but I see no value in it.
Not too many skulls are caved in in MMA.
Plenty of submissions.
