I'm not sticking up for anyone here, but what I saw was that on the first play you are talking about here, first there was a handball by an Irmo player, then there was a handball by a Dorman player that resulted in a goal. The AR told the center ref, and he made the correct call by calling off the Dorman goal and giving Dorman a free kick due to the first handball by Irmo. On the free kick, the ball hit the top bar and bounced down and the spin on the ball brought it over the line for a goal. This is exactly what happened I think it was last year with the Irmo boys, but they didn't get the call for a goal like tonight.
Believe me, I'm no Dorman fan, but it did appear to me that the buzzer did sound before Irmo scored it's last goal to tie it up in overtime, but you are right, the offical never seemed to blow his whistle to indicate the match was over.
I thought the refs did a good job until the last 7 minutes of the 2nd overtime, and then at that point they completely lost control of the game and could not make a decision.
