Rose has served as a marquee NBA agent for over 20 years with clients such as LeBron James, Chris Paul and Carmelo Anthony. He’s taking care of his current clients and businesses before decertifying as an agent to officially run the Knicks. It’s unclear if he’ll hire an experienced NBA executive to serve as GM. “That’s for ownership to determine. How do you structure an organization?” Colangelo said. “Who is the lead guy and people around him? I’ve known Leon Rose as an agent. I think he knows basketball. I think he really loves the game, etc. He certainly has a lot of relationships. I think the key in the game today is relationships.”
