MMA Submission Grappling

I was in this conversation with Mr. Walnuts this morning about people in MMA belittling the effectiveness of Brazilian Jiu Jitsu and downplaying its utility for sport fighting purposes. The truth is as a base style for MMA, I probably wouldn't pick jiu jitsu for the current structure of the game. Very few high level jiu jitsu athletes become high level MMA champions. They often also have a hyper focused skill set that doesn't relate to their new arena. Most of the elite grapplers that transition to mixed martial arts end up using that skill as a secondary or tertiary option. The reason Brazilian Jiu Jitsu became such a dominant skill set early on is two-fold 1. the lack of time limits or one very long round 2. very few people knew what was happening. The second issue won't change, people are fully aware of what submissions are in MMA and how to avoid them. The first issue probably won't change either, but I believe if someone did make single round long format fights submission grappling would regain some of its luster.
