It all depends on height.
A 6'0" 18yo trains like this with 48+ min:
Jump Shot Guards
0.53 JS 0.16 JR 0.07 HA 0.07 DR for a total of 0.83 pop/wk
Jump Shot Forwards
0.36 JS 0.07 JR 0.30 IS for a total of 0.73 pop/wk
And a 7'6" 18yo trains like this with 48+min:
Jump Shot Guards
0.42 JS 0.12 JR 0.05 HA 0.03 DR for a total of 0.62 pop/wk
Jump Shot Forwards
0.28 JS 0.06 JR 0.11 IS for a total of 0.45 pop/wk
So it's definitely a cost/benefit situation.
