OKREF wroteFair enough.. I just talked to 10 coaches and everyone of them like it. They all said it is always good to communicate, especially in late game situations.
Communication has absolutely nothing to do with telling coaches how many time-outs they have.
I have no idea what level you officiate most of your games, but I know, for me, the higher the level, the less coaches want officials bothering them.
Must be a regional thing.
