So far this season I have only focused on training my 2 centers, the next two or three weeks will be Inside Defense, then shot blocking. I will probally spend a couple weeks after that doing free throws for the team. I have a level 4 trainer and a level 1 doctor.
I am glad to head that you will make him more rounded. My personal suggestion is to only do team training like free throws when you have trouble with your minutes (can't get your best trainees 48 minutes, or it is a week where you only have 2 games, for example).
Also, when you have the cash I suggest a better trainer and doctor. Level 4 is ok but any extra edge will be what differentiates your player from the rest. Something else to consider - with a level 1 doctor you have a chance of getting a 5 week injury - which could really set your player's development back. I think with a level 5 doctor the maximum injury time is 2 weeks (even those are rare) and most injuries heal immediately after the game.
