The R disqualifies the wrong player.

[JRutledge]

Maybe it is arrogant to say this , it is not your responsibility to explain something you did not see or did not agree with. If your partner threw out the kid, that is his job. All you can do is talk to him and direct him in the right direction. You cannot explain something to a coach. All you have to say to the coach, "I did not see why he ejected your player." You are not lying. You are acknowledging that you did not see the entire play and it was not your call. A smart coach is going to understand that you did not see what prompted the call. All you can do is help out your partner, after that you are not responsible for what he might do. I know when I make a call that is not understood or seen by my partner, I have no problem explaining myself.
