stupid article. It's the kick, but nothing to do with Segal. The way the kick is thrown, it's designed to be quick, you don't see it until it's already half way up, and it's designed to split through an opponents high guard. IT's a very effective kick, but it's also quite rare. The more it's thrown the sooner it'll be figured out and avoided, just like Chucks overhand right. That one move dominated for a long time because it was unorthodox, now everyone uses it and it rarely finishes a fight anymore.
