Yeah. Hughes' kimura on Riggs was definitely a good use of a submission that we don't see very often. There are a few really good reasons why we don't see kimuras in UFC, mostly because if your opponent gets their hands free then you're going to take a couple of elbows to the face before you can resteady your mount.
Armbar and triangle are definitely somthing that we see alot on the ground, but in the heavier divisions there is alot of standing and striking so we see alot fo the guillotine takedown counter and alot of the triangle choke from people over committing while being trapped in someone's guard.
