I was saying was that I am sure that an 18 year old with superstar potential and great stats is NEVER worth 20k.
That is what you are THINKING not what it reflects in reality. Your guy was 18 year old, superstar potential PG at 6'5 and 3k salary.
What you think is good might not actually be that good. Not everyone falls for the "potential" trap and your guy was really a bit too tall for a PG to train long term as a PG.
Now as I said, with the huge influx of young guys being sold right after the draft, I am not surprised that your guy was actually worth 20k. His value obviously went up 1-2 weeks later when there was less young guys on the market so potential buyers had less guys to choose from.
