Actually, I haven't bought the Hollywood version. I coached basketball for over 20 years at all levels. I got out because I wanted more time with my family and the business is very sleezy. Just this past week, a new coach was hired at a new school and was going to hire an assistant from another team to get a player. Once the player said he would not leave, the coach took the offer off the table.
If there are seasons where your friend is only going to win 2 or 3 games, he will not be around long unless he is at high school. High school you don't get to recruit your players, unless it's a private school, you have to go with what you have.
