What do you want me to tell you specifically? I think it is an understanding, without ego which is very important, of seeing the whole play. Also, plays that are clearly in someone's primary should not have a double whistle. A delayed whistle if the primary doesn't have one and there really needs to be a whistle. If I know it is a possible area for a double whistle I will have a hammer and find my partner immediately.
I have also had someone pregame the C holding the prelim in double coverage areas. Whatever you do the crew works the best when everyone is comfortable. My definition of comfortable in officiating includes trust and knowing as best I can what the other official is going to do. In possible dual areas it will not hurt to look at your partner so you know where they are looking. Tell me if you want more specifics. I have/get to go home now.
