Well, I survived.
It was a girls JV/V doubleheader. The visiting team had 9 players... total... for both games combined.
I was definitely nervous starting out... luckily the JV game was first. Twice in a 2-minute span I nearly gave the throw-in to the wrong team (thankfully my partner corrected me before it was too late).
We had a 30 minute break between the JV and Varsity games, which gave us a chance to go back to our changing room, drink some gatorade, eat some popcorn, and go over a few things.
The varsity game went ok... The outcome was never really in doubt, as the home team had one player who was simply a better player than anyone on the visiting team... It never got closer then 6 points in the second half, and the home team ended up winning by about 20.
Coaches for both teams were great... There were only two calls that caused any sort of protest. One was a charge call that caused the Home coach to go into the whole "she wasn't set" routine. The other one was a blocking foul where I granted the H player the basket due to her continuous motion, which caused the V coach to try to convince me that there's no such thing as continuous motion in HS basketball.
The only really embarrassing thing was that the zipper on my pants decided that last night was the night that it should stop functioning properly, so there as a few-minute stretch in the second half where my zipper was loose and I couldn't do anything about it. Oh well, as far as I know nobody noticed but me.
After the game, my partner said he'd call our assigner and let him know that I did a good job and that he thought I was definitely ready to work at that level. That's always nice to hear.
