Looking at the IMDB page.
I guess they created this guy in a lab to play Larry Bird (all 10 episodes)

Mike Epps (Black Doug) is in 6 episodes as Richard Pryor
This fine lady as Paul Abdul in 6 episodes

This guy from Agents of SHIELD as Jack Nicholson

Some guy I've never heard of as David Stern
This lady as Debbie Allen from Fame, and damn.

Current Sacramento King Terrence Davis as Adrian Dantley of all people
Says Adrien Brody is only in it as at Riley for 2 episodes which doesn't make much sense since the was already on the staff in the late 70s.
Michael Chiklis as Red Auerbach, which is amazing and hilarious.
Solomon Hughes who plays Kareem was a Globetrotter and is 6-11 so good casting there.
And in the ultimate WTF moment for me - Norm Nixon's real-life son DeVaughn is playing Norm Nixon. However the son was also Danny Dyson, son of Miles, in Terminator 2. WHAT?
Also there's the role of Donald Sterling in a couple of episodes. That should be fun.
