I've been wondering for a long time if we'd ever get to the point where people trained MMA as an integrated system with the relationships between striking and grappling fully understood and standardized. It doesn't seem likely right now though places like Tristar, AKA and Jackson's have tried this approach to training with mixed success. For now, having belts in MMA can only lead to people being mediocre at everything to get to like purple belt. Maybe if you had to win a one night 8 person tournament to get your black belt.
