This play is actually from a small school league south of where I am located. I work a game or two down there most seasons. It is my understanding that the play occurred during a senior all star game, hence no back court count. I'm also assuming the schools found the officials as the assignor that sends me down there wouldn't have only sent a 2 man crew.
I may have had a flag on the play as the reciever in motion was moving forward on the snap.
