The Silva vs. Weidman has been talked about a lot lately. A lot of people call the 1st fight a fluke, saying Weidman landed a lucky punch. In the 2nd fight we have the leg break after the inside low kick is blocked. Here's a clip of the break.
So, many will say that Weidman is lucky again. Whatever, bad luck twice or whatever you want to call it, he deserves the title.
