My 2 cents on rule changes:
1. Out of Bounds Rule: Auto stall call against the first wrestler to touch out of bounds after both wrestlers go OOB which results in a ref stoppage. I think this would keep the edge of mat action as I like the current rules for OOB whistle stoppage. Freestyle rules aren't bad but I like the idea of strategy in a match and if it's a stall call then a wrestler can flee the first time without risking a point knowing that it will be a stall warning. It also takes the pressure off of the ref's from having to interpret "continued action" vs "fleeing the mat". Ref's being inconsistent on the current rule is very frustrating.
2. 3 point TD
3. Riding time changes (unpopular opinion, I know
RT can score up to 2 points: 1 point for each minute of RT -- HOWEVER, when RT hits 1 min then the ref calls a stalemate (unless back is exposed) & restart. Then auto-stalemate after each additional 30 seconds of RT for the remainder of the match. This provides and advantage to the bottom wrestler because IMO it's easier to escape from a restart vs having someone on top with the legs in or arm barred up. I also think this would create more sense of urgency for the top wrestler to create a turns (vs just hanging on) because they know a restart will happen. I'd also have RT carry over to overtime. This would cause guys to choose neutral more in OT if they are way behind in RT and be forced to go all out for a TD.
Other thoughts - Don't try to stop wrestling from the knees. It's legal and some guys can and do score from that position. It's not always a stall position as many wrestlers are very good at scoring from the knee position (see David Carr, Biscoglia, etc). ANY wrestler can stall from ANY position.
