And that is why you round the corner on the side your head is near for a double-leg. He actually had the turn perfect, then switched back to try to power through the slam. I'm guessing he won't be making that mistake again anytime soon.

That's bizarre! Has that ever happened before?

it was actually ruled as a no contest... none of the fighters won the fight and they are going to schedule a rematch, even though maynard was clearly winning the fight.

...and thats the first time that happened in the ufc.

You mean a double-KO kind of situation? Actually, Boom, I can think of twice in the UFC. Hughes vs. Newton 1, Newton locked in a triangle choke from guard but didn't break Hughes's posture, so Hughes picked him up and slammed him. Newton was knocked out immediately, but Hughes also went sorta limp, either because he dropped head-first into the slam or because he'd gotten choked out, although Hughes kept going and was awarded the controversial win. There was also a TUF fight where one guy took a wicked body shot, doubled over, then straightened up to connect with a wild haymaker for the KO, and then collapsed himself. Although I can't think of another situation in the UFC particularly where both guys went down at exactly the same moment.

Double-KO slams aren't all that rare in MMA, particularly. I've seen them a few times in amateur events, and a bunch of times (not really KOs, maybe, but both guys getting totally stunned) in hard sparring and smoker matches with guys who were never taught how to perform a proper shot.

The standard double-leg takedown that is practiced in MMA is the wrestling, not judo, variety. Notice in the video how Yamamoto makes his penetration step with his lead leg, drives in to his knee, then brings his rear leg past that to pop up to his feet again, driving sideways with his head while blocking his opponent's far leg with his knee. This allows him to pick the guy up sideways, so his opponent can't pull his head down if he gets a guillotine-style headlock. This is called "turning the corner" in grappling, and it's drilled into fighters' heads from day one.

If you don't turn the corner on a double-leg and instead drive in judo-style, and your opponent gets that guillotine control, you'll end up dropping both your and your opponent's weight onto the top of your head as you hit the mat. It's a beginner's mistake, though, and I can't really figure out what Maynard was thinking.

His name is actually Gray Maynard, not Ray.
