Jones used to always land those spinning elbows to the back of the head, that's how he dropped Bonnar. He's changed it though, he used to come down from the top now it's from the side. If they land to the back of the head, they are illegal, just seems like refs never see it as that.
Those oblique kicks are pretty lame though, just like the punches to the thigh. The point is to hurt the other guys knee, which is pretty dirty.
