I used to DVR Pardon the Interruption and watch it every night after work. At the time I wondered why they never discussed MMA as it became more and more popular, especially after the second Chuck/Tito fight. Around the time Chuck and Rampage II happened they did a small segment bashing Chuck and saying similar things as they are now. Wilbon wasn't as bad, but Tony clearly loves boxing. I haven't watched it since that time and figured they would have learned more about it as it became more and more mainstream. It's sort of sad to see such a popular sport show still remain ignorant of how complex MMA really is. It kind of reminds me of a professor several years ago coming into my Philosophy of Mind class after it was over and saying, "Why not do philosophy of the foot?" He just didn't get it...unfortunately.
I think SportsCenter has gotten much better and they now have MMA Live, which you didn't see a few years ago.
