There is a famous Australian guard Loc Ðinh (16764939) who was on the U21 team whose manager trained his JR to the levels you suggested about 18 or so with JS about 15 (both from memory). His salary is just massive ($156,000), he is constantly on the TL as one manager after another sees how useless he is, he scores a lot but at a bad percentage (45% last season, 47% the season before despite playing against weak division III and IV defences, I see players with 1/3 of his salary score a similar percentage against much tougher opponents) and doesn't help his team to win all. When a 26 year old HoF guard with a $156,000 salary is constntly on the TL and sells for $340,000 it really tells you something. I hope when they make the mid-season changes they do something so players like this are not so salary inefficient.
