Quote: It's funny how teams that play tough D and keep their opponents to a low scoring number are usually low scoring teams as well.
Few players can do it all well, so a good coach needs to pick and choose who is going to get some free time on D so they can light it up on the other end.
You're correct.
An extreme case would be high school teams. If you can score, coaches will let you relax on defense so you can conserve energy and not pick up fouls.
