Agreed. I'm not offering help on this play unless it started in my area. I have no business knowing who hit the ball out, and if I do know I'm not letting anyone in on my little secret.
I had a partner earlier this year that did the flip side of this. 2-whistle, I'm T. Ball goes OOB on a rebound, and he blows his whistle and looks to me for help. Not a good situation.
