That's an Adidas sponsored shirt btw.
I wonder what clothing manufacturer Ben Simmons is represented by.
You can find the Adidas logo here. I didn't use this pic because it was grainier.
About when to consider someone a rookie:
How do you handle David Robinson? He joined his team 2 years later because of his commitments to the Navy.
What about Jerry Lucas? He decided to play in the ABA instead, for a year. He was drafted in 1962.
After that, he joined his NBA team, the Royals, in 1963.

How do you distinguish someone who has spent a year with the team, like Ben Simmons and Blake Griffin, vs. Jerry Lucas (who played in the ABA instead of the NBA) and David Robinson (who was not around the team)?
Maybe they can say something like your rookie year starts the minute you sign that rookie contract. That way, you can't be around the team until you sign the contract.
But now I see that David Robinson actually signed in 1987! LOL. Maybe he should have held off until 1989.
But then what if he got hurt at the Navy?
Still, I guess it's a better system.
It would have eliminated Griffin and Simmons from being rookies because they signed their contracts and were around the team while hurt.
And maybe Jerry Lucas could have waited to sign the contract until he was ready to play in the NBA. Actually it appears Jerry Lucas was drafted by both the ABA and NBA, and he chose the ABA first in 1962.
So he still could have chosen the ABA in 1962, then switched to the NBA, the other league that had drafted him, in 1963.
