I think a lot of people on here are being too hard on the ref. This position happens all the time in wrestling matches and I can’t remember another time someone way choked out with it (I am sure others on here may have seen it before but it is certainly uncommon).
chech out the sequence from Kemmerer’s match at 34:24 and com pair it with Case’ match at 48:00. The arm is in the exact same position. The only difference is that Ken has the Turk and Cass does not. Also that Cass’ opponent pushed back into the arm harder (probably could push back harder without being turked).
Watch the clock and how long between when Purdue goes out until Cass releases the neck and adjusts. It looked like 3 seconds at the most. As soon as the Purdue wrestler stops pushing back into Cass he adjust off the neck.
I think the ref could have done a little better, but in real time with counting back points, watching for the pin and watching the move I don’t think it was as bad as several here are making it out to be.
