I officiated HS basketball and summer tournaments for a couple of years. It was stressed every single year and even during midseason meetings to be consistent: every trip up and down the floor, every quarter, every half. To be a good official, you cannot 'let them play' for a quarter, a half and then start calling every contact. As the skill level increases, we were told to allow the players to play a bit more. But, parts of the few CBB games I watched this year looked a lot more like a rugby/hockey game than basketball. A ton of lowered shoulders to create room for a shot, a lot of handchecking, a lot of very physical play and, to my eyes, missed calls on shots. Makes for some really bad basketball at times if every shooter is physically checked on their shot. If players understand early what will and won't be called, the game, from the officials' standpoint, moves along much more smoothly. When the calls seem like they're all over the board, that's when coaches, players and fans start giving the crew a ton of grief.
