I get why some don't like it, but it's an integral part of MMA. It's appreciated by many people, especially those who have wrestled and can understand what's going on via watching. I only wrestled in high school but I can recognize how incredibly difficult and exhausting it is. But most of all, I can appreciate the skill it takes to manipulate another persons movements and position. Lay and pray does not equal wrestling. I'd suggest watching some wrestling training videos so you can better understand the intricacies of every little movement, weight shift and grasp of their hands.
You're short changing yourself as an MMA fan if you don't learn what wrestling is, because you clearly have the wrong impression.
