Wow SMitty. Your cynicism is showing.
Ever heard of psychology? Ever heard of of being courteous? Don't you believe that any time you can reach out to someone in a stressful situation it can set a positive tone for the day?
Of course the first time I call his PG for a charge he'll be hacked off, but it can't hurt. Or don't you believe in managing the game and just want to blow the whistle when you see a violation?
There is a psychological theory called piling on. Each negative occurrence emotionally stacks up on top of the individual and can cause a lack of control. Subconciously, positive interaction can reduce this tendency. Again, an easy little game management thing. Probably only changes things once a season, but its still a positive action.
