I was there and Coach Letton was indeed on the field. The penalty was never intended to be an unsportsmanlike conduct/personal foul on Coach Letton. So, yes. I do believe that the penalty was appropriate. In addition, those saying Coach Letton ran to the middle of the field in some sort of barbaric tirade are simply untrue. There was discussion amongst the officials at about the numbers, and coach walked out there. Pretty normal IMO.
