It's a bit unfair to say people aren't understanding it because they think it is boring. What is there to really understand about the ground game? They get on the ground and wrestle around for a dominant position and wait the round out, bludgeon the opponent or try to use a choke or submission to make them quit. I wouldn't agree with someone who says that those things take no skill but that has no bearing on whether or not I want to watch it. I think it is a bit of a joke to assume not enjoying something equals not understanding it.
