Mayweather calls out UFC and MMA as a whole...

[MikeyPatriot]

If you've only seen UFC, that's probably a reason why you find the ground game boring. NSAC rules don't allow for knees or kicks to the head of a downed opponent or stomps. I don't think the kicks/stomps are a big deal, but not allowing knees to the head takes a lot out of the ground game.

You might want to try and check out some Pride, specifically Fedor, LDO.
