Ok, maybe I missed someone else saying this but .......... you are a referee turned coach right?
So, you should already know the procedures, consequences etc.
Ok, so you didn't get a horn at 20 seconds. That does not mean you don't have to have a replacement in by 30 seconds and you already knew that. You obviously also weren't coaching too much you were "freezing" the shooter and had your replacement standing there waiting to send in. Sounds like you kind of "screwed the pooch" on this one playing games.
Do you think that "freezing" the shooter for 30 seconds is any more effective than "freezing" them for 20 seconds especially at a freshman level?
Come on - GET OVER IT! Ya blew it earlier in the game when you already earned one T. As on ex-official you should know where the lines are. Even if the
TIMER didn't follow procedure - the official did when he gave you the second T for not having the sub in. Their only screw up as I see it - is you were not ejected and for that - at least in my state - you can be thankful!
