Well, for me, its the smile, the challenge, the team work skills, the obvious fun he's having.
We all get cut at some time. If a few extra bucks will give him the skills, enthusiasm to practice/develop, self confidence to score another season in a starting position then I'd rather spend the $$ there than going out to dinner, buying the more expensive bottle of wine. And I can get another year out of my old junker car.
I do the same with my other kids and their chosen sports. Play College.....****, who knows, something of a gamble. I tend to take the short term view and encourage general physical fitness, education, and fun thru sports. Everything in moderation including baseball, showcases and high level travel teams.
