How to improve player abilities in Association

[L1VINGL3GACY]

Is there a way to improve player abilities in Association?

Right Now i have an association with the 76ers and i want Marreese Speights (i know he doesnt play for them anymore. Started this Association as soon as 2k put the rookies in)

I want to improve his player abilities. Here they are

Post Drive - Poor

Post Spin - Average

Post Fadeway - Good

Post Hop Shot - Average

Post Shimmy shot - Avearge

Post Hook - Average

Post Drop Step Layup/Dunk - Average

Is there a way i can improve these to make him a better post player?

To improve the players abilities specifically the Post Drive and Post Spin abilities use the close range weekly practice. I tested it out with a simulation Hawks Association and after about 3 weekly practices all the players had permanent Great ratings for Post Drive and Post Spin. The other post abilities seem to increase as the player progresses in the offseason.
