CrossTrainer and I used to talk about how we wished their would be fights under these rules: MMA Gloves 5 minute rounds No kicking (kneeing was up for debate) Elbows are legal Standing submissions are legal (another debateable one) Takedowns are legal but broken up once completed (could either allow all takedowns or just upper-body takedowns like Greco-Roman wrestling) Clinching allowed and given a lot of leeway Holding and hitting allowed. Possibly headbutts allowed. It would be pretty similar to the earliest boxing matches in a lot of ways.
