Coaches should conduct themselves in a manner that brings respect to their institution and the conference, understanding their responsibility as an educator and a role model for their athletes.
Coaches may discuss calls with officials in a respectful manner at the appropriate time as stated in the rulebook - during timeouts or between quarters. Discussions with officials after a game should take place in a location removed from spectators and players.
Coaches are expected to demonstrate good sportsmanship. At no time should coaches publicly criticize officials.
Above all, coaches should always be a positive role model for parents, spectators, and players.
Part of official education is to improve communication when making calls in a game, usually with the use of hand signals. Remember that if you do not see a hand signal, it does not necessitate yelling to the official about what the call was for. Instead, please seek clarification at the appropriate times (timeout/between quarters).
A quick question of "I did not see what the call was for, can you please quickly share what happened?" resolves the situation in a collegial manner.
The action of yelling to an official across the pool deck is in opposition to maintaining good decorum. Instead, approach the officials at the appropriate times to have a normal voice level conversation. This action reduces the opportunity of misinterpretation of intent and allows for a constructive conversation about the game.
