The question isn't "Should he go," but "Are there enough spots for him to go?" Nowtizki, Gasol, Durant, Anthony, Beasley, Love, Griffin, Gay, Scola, West, Aldridge, Millsap, Randolph, and Jefferson are all scoring better than him. Love, Randolph, Griffin, Gasol, and Camby are out-rebounding him. Duncan's numbers per minute are better.
He may go, but it will be because of the name recognition of being a Laker if he does.
