Priorities:
1. inside shooting (teams with high inside shot usually gets a high FG%, thats great offense)
2. both ID/OD (you're going nowhere without defense)
3. PASSING ( you should prioritize this because it will make your offense flow better which will make your FG% rise)
4. rebounding (to secure defensive rebound and get some offensive rebound)
I did not add outside shooting because i noticed that some teams even though they have very high outside shooting they are not still consistent with their three pointers. Plus, I think that no matter how high your outside shooting is it will never be 55%+ on average. (ive seen teams with good inside shot they can get FG% as high as 60% on average)
