How does he not know Big Z or Hedo?

I read a story Cooper that his Mom during car rides to games would play DVD's of the 1980's Boston Celtics games. I bet you he can identify Danny Ainge and Scott Wedman.

I can't wait for the next Gil's Arena episode when Gil clowns Rashad McCants for Cooper not knowing who he is. Rashad thinks he is a superstar in his head.
