always looking for someone to roll the practice balls out.
Can't stop a head coach from hiring a full-time assistant who does just that, but it's still an important limitation because each team is limited to three full-time assistant coaches. When you hire an elite player's dad you're giving up one of those three coaching positions, so if the guy isn't a contributor to the coaching staff, it handicaps the head coach in that way. And the dad/coach has to be at practices, be on the bench at games, has to be visible in the ways assistant coaches are; he can't be sitting at home all day just cashing paychecks.
It's far from perfect, but it's better than letting the likes of Cuonzo or Enfield pay a 5-star player's dad $150,000/year to be a "special assistant to the athletic director for basketball affairs".
