Here's a question for you: do those sports have the same types of coaching licensure that soccer does? (or any at all?) None of the parents who coached my children in baseball, basketball or softball had any kind of license. I knew several people who coached football, and they definitely did not.

Excellent question! Licensing primarily serves to make money for USSF or NSCAA. I read an article in the last NSCAA Journal about a high school coach that has won more than 800 games and multiple state titles, but has no license. Is he a worse coach because of it? Or is a "dad" that attends two weekends to obtain a "D" license a better coach because he's been "trained?"
