The size of 1500 shouldn't really be a factor. That is plenty to pull enough good athletes from. And as far as organizing and managing the program, I've seen much smaller schools consistently succeed and larger ones fail miserably.
Thank you very much for your perspective, cabbagedad. I really appreciate it - exactly what I was looking for.
From what you describe - it sounds like our high school has a reasonable (average) baseball setup and I should express appreciation for that at every opportunity.
I agree that 1500 is plenty of students from which to draw enough good athletes. Turns out that the 2023 and 2022 age cohorts in our town happen to be way above average, so our school will likely win a lot of games a couple years from now.
The reason I started this thread was to get an understanding of what kinds of expectations are reasonable. Sounds like off-season group conditioning programs led by head coach of a HS baseball program are the exception, not the norm.
