Friday night - 2nd of 4 games.
A is passing the ball around in their frontcourt. I'm at trail, and my partner (lead) blows the whistle when the ball goes off of B and hits the bottom of the backboard. I clearly saw that it hit the bottom, so I went over to try to talk to him about the rule. When I was standing right next to him, he put the ball in play, and then had to blow it dead realizing we needed to talk. Needless to say, the call was not changed.
At the next timeout, all the other staff was reaming me out for trying to get this guy to change the call - saying it "looks bad" (of course, they didn't know that the bottom isn't OOB). So, this sort of thing is bad, but it's fine for the trail official to whistle the OOB on my line at lead.
Sorry for the venting. Just consider this part 49198471 of why to never work rec ball.
