Human behavior tends to be biased, naturally. This makes oversight necessary in all aspects of human existence whether it be traffic laws, criminal laws, regulations, or simple adherence to rules at a sporting event. There is always someone trying to get around the rules, laws, regulations, etc.
In the case of officials, a preconceived reputation is often of great influence. IF a pitcher is said to be wild, he is unlikely to get close calls on the corners. If a player has a repuation for quickness, steals may well be permitted that involve a little extra, like slapping a wrist or hand. If Griner blocks a shot by Vegas, the officials are more likely to call it a block than if Vegas were to block a shot by Griner. They didn't quite see it, but Vegas just can't block a Griner shot. Do you call the game or what you think you saw?
This isn't rare. In any human activity, reputation influences the opinions of those regarding the facts in a case. Perhaps, unfortunately, it is now the job of a coach to precondition the opinions about his/her team.
You also see officals get caught up in the emotions of an activity. If a team makes a comeback at the end of the game, especially if it is the home team, a few transgressions are tolerated during the run that would have been fouls earlier in the game. Some officials go as far as to exaggerate calls in the heat of emotions.
There are times that calls are under some outside direction. When an official makes five traveling calls in two minutes at the start of the game, and none thereafter, he was probably instructed to pay attention to traveling. In pro basketball, former officials have stated that they were influenced to protect certain players. I don't know that this is done in college, but if there is money in it, it wouldn't surprise me. That is the motivator.
Officials are human. To suggest otherwise is naive. In order to maintain a consistent and effective flow, there must be oversight. This often breaks down, whether in sports or otherwise.
