Although I agree with you, that is somewhat my argument that says class wrestling (while it may help wrestling) may not be the best solution for the kids. The flip side of your argument is this...
Why do some parents move their child from large schools to the smaller "country" schools?
- More individual attention
- A chance to be a starter (and/or possibly a star) at sports where they may not even make the squad at a large school
- Environment where everyone knows each other
Your comment "throw the other sports they most likely are involved in" is framed as a negative thing. I would contend that it is not. If your child's goal is to be a possible college wrestler, then by all means focus on the one sport, put "more emphasis on club and off season wrestling". The 2-3 hour drive for a quality club is definitely an obstacle, I will agree with that.
However, since this is a wrestling board, these arguments always focus on the issue through the lens of the wrestling community only. One of the wonderful things about small schools is that a student can be (and is often expected to be) part of the football/wrestling/baseball/track teams. And also be in the school play, student leadership, etc. Rather than see it as a problem, I see it as a benefit for the majority of students who will not go on to play sports in college. Since there is a team state, if the small schools see success at that level and want to be a part of it then that is a great selling point to get more kids out and fill the lineups.
