I would never overrule my partner.

I have brought in information to my partners when it was OBVIOUS it should be different (but only on violations). I have also been asked for help on a tip they were not sure who it went off of. I have also had a partner come up to me say he knows he kicked the call and that he's going to give it to the other team (I didn't have to say anything).

I never discuss/help on the floor a partners foul call (be it charge/block etc.) as it shows the coaches that I'm running the show and I don't feel my P. is strong (we are supposed to be a team). Those are left for discussion at the next opportunity (T.O., Quarter/Half time) then I only ask what they saw on that play. You may want to discuss in your pregame a hand signal for each other to tell them to remember that play - this makes it easier to discuss later on.
