I'll just sum up the 3rd period for you. Cashe's up 2-0 and Harper chooses top. Harper rides and tries to turn while Cashe keeps a strong base. Then, inexplicably, the ref hits Cashe for 2 stalls with about 30-40 seconds left for doing, virtually, the same thing that he was doing the first 1:30 of the period. This is the single reason why I hate mat/riding position. It's not necessarily the wrestling part, it's just at what point is the bottom and/or top guy stalling? At least in the neutral position, it's a lot more clearer in my opinion.
