By 18 players should not be "learning" different positions. That should have been done way before 18. Club ball at that age is all about getting noticed by some recruiter. You wouldn't take some 6'3" middle and make her a DS at that age. If someone has played a position for years, and all of a sudden they need her to play some position she's never played before, or very little, that's not fair to her. Her parents paid the same as everyone else and I'm sure they're as frustrated as anyone. If a boy played summer AAU b-ball for 6-7 years as a point guard, and at 18 his coach tells him he has to play center,just when recruiters start paying attention, that would be ridiculous. With the money it costs to play club, parents should have some say in the matter.
