Stole this from someone else but I am changing it a bit.

You can buy a player that will have all of his boosts paid for with no discount. If you retire before he reaches an old ass age you dont get anything back other than what you would have originally received if he retired at the appropriate age.

It does help you to know right away if you just want to buy your shit and be done with it.

This shouldnt be on the NGTH list.
