That really depends if you wanna count with him in the starting five really early or if you can sacrifice some seasons and use him during cup/friendly matches!
Your comment is based on a direct good performance. Mine is more an advice to have a really good player in a slightly slower way but that can give you nice results in a near future.
This player was like this with 19 years old and 5 weeks left to the end of the season:
(11783015)Jump Shot: average Jump Range: respectable
Outside Def.: prodigious ↑ Handling: prominent
Driving: proficient Passing: respectable
Inside Shot: strong Inside Def.: proficient
Rebounding: respectable Shot Blocking: atrocious
Stamina: inept Free Throw: inept
By training only pressure he manage to have several pops in Handling, Driving and Inside Defense (besides OD of course).
This is just one example of how you can get advantage of the slightly fast train of pressure when they are young. And the player is still useful for the team if you want to stop a good PG/SG.
