I don't know if anyone else has mentioned this. I was watching a WEC Wreckage I had DVR'd last night, and there was a pretty good bantamweight fight on with some excellent ground fighting on it, and in the middle of it the crowd start booing becuase there is no "action"
I don't know about you guys, but every time that happens, even in slow fights, it pisses me off.
I understand that knockouts are exciting, but to me, the best part of MMA is the technical ground fights. The passes and counters until one of them makes a mistake and gets subbed or mounted and pounded out.
It seems that if they don't throw a punch within a 10 second period, people get restless and start booing. This is embarrassing to me for the fighters, and the sport, and makes us look like profesional wrestling fans (I have no problems with pro wrestling, but you're supposed to boo in that, it's part of the entertainment).
There are a few exceptions though, like the Kalib Starnes-Nate Quarry fight, where starnes was literally ducking Quarry. I probably would have booed Starnes too.
