I went to the Emerald at Walhalla game because I knew it was for the region and the known rivalry. I did not have a dog in the fight, but I will preface this by saying I do know the Walhalla coach.
IMO, soccertennis reports the match with Emerald colored glasses. I thought it was one of the better matches I have gone to see this year (around 20). Not the most talent I have seen on the pitch (some very good individual performances on both sides), but a pretty even, closely contested, exciting back and forth match.
As far as the altercations between the players, I only saw two involving the teams during the match (one in first half and the late one). I have seen a lot more than that at some of the SCISA matches I went to see. I was standing near top of stands at about the half field stripe and saw the second one. #15 for Walhalla definitely pushed #11 after play stopped and was given a straight red, however, #11 from Emerald did give #15 a forearm shiver to the chest that lead up to the push although not called even though the side ref (3 refs) was standing right there. Another case of second act being caught/punished. It is my observation that it is never just one team being overly aggressive or doing all the instigating as you imply.
It was explained to me (I am no ref) that #9 from Emerald got the second yellow / red (he had gotten a yellow earlier in the game for a bad challenge) for touching/moving the ball after asking for 10. Maybe a current or past ref on the board can explain if this is a yellow offense? Otherwise, I can not imagine why he got the second yellow.
I did not hear the profanity you say the Walhalla players were saying, but I was at the top of the stands. All I heard were the players from both squads talking to each other.
I do agree with you that time should have been added at end of second OT for the goal/celebration and the one fan (not fans), that ran onto the field and joined the dog pile celebration. He should be banned from future matches, but I do not see how you can blame the administration for an isolated "idiotic" fan. They went after him right away and made him leave the stadium. I do not think Emerald could have leveled it being down 2 by adding another minute or so, but they still should have added the time.
Congrats to both teams on a great match and they very well could meet again in the upstate portion of the playoffs - not sure either team has a chance against Bishop England.
