I agree. Luke did a fine job when Steve Kerr was out, but everything about the Warriors is different than what he would find in the Laker organization. Another year or two with the Warriors wouldn't hurt him. Steve Kerr is a great mentor, the Warriors are a finely tuned organization, and Luke is bright and capable. I think it would be an error for him to begin a head coaching career in LA. As you said, Buss needs to go before that team gains competitive traction. Probably a bad choice, IMO, if Luke took that job.
