Welcome to the club, Ace
You know, I almost posted this a few days ago when it happened, and didn't. But I'll throw it out now.
Freshman girls. Six seconds left in the game, visitors up by two. I'm watching off ball. My partner calls the visitor's guard for a push. Crowd, coaches, and players go ballistic! Amidst the howling, we march determinedly to the other end and shoot two free throws. Home team ties the game and wins in overtime.
It isn't until I'm in the shower that I start to get that sinking little feeling. I call my partner, ask him specifically if the foul was on the ball handler. Yes. The girl who actually had the ball, she was dribbling the ball when she fouled, correct? Yep. AGH! He was not aware that we don't shoot free-throws on PC fouls.
Emailed the assigner that night and fessed up. Talked to him on Saturday and his response was classic: "That's one mistake you'll never make again." He's right.
Set it aside and move on.
