Yep, they gotta retire it. Now, will Shaq act mature and respectful if the Lakers do it? Who knows... thats the side of Shaq I hate. He whined about Orlando for years until the Lakers angered him... now he's whining about the Lakers, although more subtly.
He is a great player, just a big egotistical baby in my opinion... then again, so is Kobe... they DO belong together... HAHA (just kidding!)
