System is the last thing I’m concern with. It is one notch below my concern for kids transferring. As a former high school and college athlete, I never gave a piss about who the other team is or how it was formed. I just wanted to win and when it didn’t happen I didn’t find an excuse other than we got beat. Same way I raised my kids. IDC who they played or where they came from. Just go out and find a way to win. If not a win, don’t make excuses.
Im guessing you had similar DNA and taught you kids the same thing.
But that’s just a guess.
