Poor Game Management: If Coach Schrewberry frequently makes questionable in-game decisions, such as bad substitutions, not adjusting to the other team’s strategy, or being too slow to call timeouts when needed, it can make fans and players alike lose confidence in his ability to lead.

Lack of Player Development: A good coach not only manages games but also helps players grow. If his players aren't improving or learning new skills, it could reflect poor training sessions or a lack of individualized attention, which is a critical part of a coach's job.
Inconsistent Performance: If the team is wildly inconsistent under Schrewberry—losing to weaker opponents or failing to show up in big games—it might seem like he’s not motivating the team or preparing them mentally for high-pressure situations.

Questionable Team Chemistry: Sometimes, a coach’s style can create a divided locker room, whether through favoritism, lack of communication, or not managing conflicts effectively. This can lead to a dysfunctional team, which affects performance on the court.

Defensive Strategy Issues: If Schrewberry's defensive systems are constantly exploited by opposing teams, or if the team fails to execute defensively, it shows a lack of preparation or flexibility in his coaching strategy.

Poor Offensive Schemes: Similarly, if the offensive sets are predictable or fail to take advantage of players’ strengths, it can lead to stagnation on the court. A good coach tailors his offense to the personnel he has, so if it's not clicking, it could be a sign of weak coaching.
