One of the things you hear more and more in combats sports (in particular in MMA) these days is that “leg kicks don’t finish fights.” Somehow, people are under the impression that therefor the leg kick is not a worthwhile technique. Not just in the cage but outside of it as well. I know for a fact this is patently wrong, they will fuck up your week. As always, it depends on the person throwing that kick, the circumstances, etc.
