Not all encompassing and in no particular order:
Where kids are more important than the team. Parents more concerned with position, playing time, and recruiting than winning.
Where coaches aren't willing to put the time into preparation and/or building a program rather than just a team.
Lack of or inconsistent culture.
Bitching about opponents having unfair advantages.
Avoiding playing teams that would make your team better.
Unsupportive administration.
Lack of a sufficient strength and conditioning program.
Coaches who are unwilling to adapt their style to the different personalities of players and coaches.
And obviously too many free lunches. 🙄
