"Judgment calls" are what we do...

[Travelling Man]

Various rules-making organizations have earnestly endeavored to establish "rules" for basketball play; furthermore, these organizations regularly convened committees and training programs to--dare I say--establish "interpretations" for such rules. We all appreciate and benefit enormously from our "rule books" as they establish validity, reproducibility, and credibility to our officiating profession. Yet, a rule book cannot possibly predict nor legislate all possible scenarios that occur within a competitive hoops game; therefore, we must use our judgment.
For example, when coaches compel their players to "play hard/tough" and their actions/style of play then influences the opposition to "play hard/tough"---which in turn causes officials to use their interpretation and "allow" such a style of aggressive of play because we don't want whistly "ticky tack" fouls.
As an example, last night I reffed a game where the coaches were encouraging a style of aggressive play--like hard defensive hedges on screens, strongly pursuing 50/50 balls, and the such. So, we must use our judgement to enable the "game to be played" instead of whistling every little tap or touch--within the confines of fair play. In short, we must use our judgement.
