just a simple reminder that every wrestling ref I've spoken with (which is several 100; probably more), in which we've discussed pins, has never once indicated that anything like what's mentioned in the quote ever enters their mind. And on the flip side, I have 100s, perhaps 1,000s of experiences where fans, coaches, and other wrestlers are certain that a pin was missed (and not bashful about stating as much), where the pinning area was 1/4" or so above the mat, or the pin was not held long enough (which is not a factor in college). The ref is in a far, far better position to determine whether or not there was a pin than is anybody else at the match.
I'll also add there are some situations where a ref is almost certain that a pin has been accomplished, but due to how the wrestlers are positioned it is impossible to determine that. You can't call something based on what you think likely is taking place. The ref owes it to the defensive wrestler, and to the integrity of the sport, that they can determine 100% that the criteria for a pin has been met before calling a pin.
