2. Knows the Spurs’ system
When a player comes to a team, it is important to learn the system quickly. The new arrival must understand his role on that team and perform it to the best of his ability.
The San Antonio Spurs have a system that’s worked for them since Gregg Popovich took over. His defensive schemes have had the Spurs near the top of the NBA in defensive rating year in and year out. He also has effective offensive schemes that play to the strengths of his players.
Belinelli should be able to slot back into the system, providing his valuable skill-set off the bench. This is due to Belinelli being indoctrinated into the system last time he was with the Spurs.
However, it is not just knowing the system that will help Belinelli. He also knows the coach. If you watched the jersey retirement ceremony of Tim Duncan, you would know that Popovich has a particular way with players. He expects the best out of you and if you do not give it, he has a very upfront way of telling you.
Knowing how to please the coach and how to take the roasting that he can give is half the psychological battle for an NBA player.
