It’s right there in the NBA rule book to see. Rule No. 12 A., Section II a. (9) says “A delay-of-game shall be called for a player entering the game when beckoned by an official with his shirt untucked.” “It was overlooked,” Thunder center Steven Adams said. “I don’t think a lot of players or people have read the rule book. I hadn’t seen it ever until he brought it up. I didn’t even think it was a thing until he brought it up. “I think he (Paul) brought it up and they made it a point of emphasis. Fair enough. You have to stick by the rules.”
