I found vjl110's model predicting career arcs for draft picks fascinating and put together a snapshot of every drafted high school player from Kevin Garnett on according to his thresholds.
Star= Greater than 10 WS
Stud= Greater than 7.5 WS up to 10 WS
Starter: Greater than 5 WS up to 7.5 WS
Bench: Between 2.5 and 5 WS
Bust: Anything below 2.5 WS
Important Note: I made no distinction between WS and WS/48 minutes. If a guy played 10 games, even ten great games, I only went with total WS. Obviously guys who were injured or played limited minutes when young suffered. This is only meant to be a snapshot, not an entirely comprehensive account.
