Boozer's a lot like Kanter really. All offense, no defense. Average height with limited length, athleticism and worse, defensive foot speed and reaction. Likable guys but with a sort of semi-douchey public persona and inability to see their flaws and care about them. They're also guys who you think could be a key starter because of how strong they are on offense with the hope they'll "get it" and improve on defense. And they never do. Ever.
But Boozer was one of the top passing big men and Kanter is one of the worst passers in the history of the NBA. Kind of a huge difference maker.
