Fishing in someone else's pond

I think there is a difference between having the angle on a play in your secondary area and calling a violation right in from of your partner from 40'. Trust your partner. If he needs help, he'll ask.

Also, I agree it sounds like you were ball watching. It's a hard habit to break and you will find yourself in more situations like this if you don't concentrate more on your primary responsibilities.

And rainmaker nailed it - pre-game!!!!!
