And it begins...

1. most of the players are looking to find a "scapegoat" for their diminished playing ability. They will hollar "and - one" when they try for any contested shot --especially layups--which they will frequently miss in the face of slight defensive pressure. But do NOT be dis-armed by this as they are just missing contested shots.
2. Do call fouls frequently to keep it under control
3. Do issue technicals.
4. Maybe it'll be helpful to hold a brief pre-game conference with them prior to the start of game to clarify rules of play.
5. Have fun and continue to enjoy reffing!
