It all boils down to intent. Tyron’s primary intent was to get the takedown, which is to put Condit on his back. His intent was not to cause a fight ending knee injury. How many times has Woodley hit that takedown on somebody? It’s probably in the hundreds. How many times was someone injured because of those takedowns? I’m guessing not that many. Even in the UFC many people are taken down with a variety of techniques and you rarely see a devastating injury as a result. It has happened but not very often. Tyron could also have been intending to do harm to Condit by taking him down but he could not have known it would blow out Condit’s knee. Contrast this with a submission master’s intent when going for a knee bar or a skilled striker going for a KO punch. Their intent is direct and evident in the technique itself. Anderson Silva versus Chris Weidman was another fight people deemed to be a fluke. In that fight the technique Weidman used on Silva to break his leg has the intent of blocking the kick but also of hurting the opponent’s leg so as to discourage future leg kicks. The attacking leg is the primary target. Woodley deserves credit for getting the takedown but as far as him finishing Condit, it was a fluke.
