We had an IW on a play where there was illegal motion on the running back. For some reason, as soon as the play (ball) was in front of me, a whistle sounded. Of course everyone stopped except the ball carrier who ran 50+ yards for what he thought was a TD. Guess he wanted the exercise. At the end of the quarter a coach is on me about the IW (it wasn't me) and I explained stuff happens, hopefully won't happen again, sorry it happened, etc. Sure as hell, about three plays later it happened again, by another person. Sure made for a long first half, but we all learned a valuable lesson. The IWs had no 'effect' on the outcome of the game, but it sure showed a lack of competence that was uncharacteristic for our crew.
