As it stands, there are a few rules that make MMA very anti-wrestling. Rounds ending and being restarted on the feet, fights being stood up when there is not enough activity, and allowing upkicks to the face on the ground of a standing opponent but not allowing soccer kicks to the head from the standing fighter to a grounded opponent are some that come to mind -- these are factors that would not apply if a real fight were to unfold.
If I fought someone where no one was around and there were no rules, no one is going to make me stand up because I'm not doing enough damage. Also, after a subjective amount of time, no one is going to make me stand up and give the other person a fresh start. However, in a real fight, damage will reign supreme over positional control, which is what the current ruleset reflects.
The ugly truth that no one wants to admit is that if a real fight were to occur between 2 trained professionals and they avoided groin shots, eye pokes, punches to the back of the head, etc, it may simiply not be that entertaining -- grappling is just that prevalent in fighting and folks don't want to accept it. I get it -- watching someone lay on top of someone else is very boring. However, so is watching 2 counter strikers dance around each other. It goes both ways imo.
Thankfully, for those that don't like wrestling in fights, there is kickboxing, bare knuckle boxing, powerslap, etc to keep them entertained. MMA doesn't have to be a sport for everyone.
