We've seen just about every submission possible in the MMA world, from the kimura to the armbar, to the heel hook, and heaven only knows how many versions of the triangle choke we've seen.
In addition, we've seen rear-naked chokes, arm-triangles, Achilles' holds, guillotines, the Americana, the north-south choke, and last year, we saw the Twister.
Now, this year, we saw the calf-crusher, but there's still a bevy of other submissions in the MMA world that no one in the MMA world has seen in a sanctioned MMA bout.
What you're about to see are ten submissions that have not been pulled off in MMA, and allow me to let you know in all fair warning:
There may be only about two or three that could actually be pulled off in MMA, but all of these submissions are on an insane level of pain if you know how to lock them just right.
