I had replied earlier, but it didn't post, so here it is again. Its a little long, so I apologize. I was a wrestling dad for 2 boys for several years and didn't always agree with the officials calls. I want to preface my comments with the fact that I was not present and did not see what happened and thus can only speculate. I agree that the reputation of the wrestler should never be taken into consideration when making a call.
Upsets happen all the time.
Just look at this years march Madness. For the match in question here, the wrestler that lost was obviously a good wrestler since he was a state qualifier and many kids wrestle above or below what their records and reputations would suggest they should do. The state tournament is a major brain fry. My original posts were generic comments about stopping the match during pinning situations. They didn't necessarily address the specific issue at hand directly.
