kg wont always play the 5 to end games. against the magic, he will not be guarding dwight. that will be where bbd probably ends the games with garnett at the 4.
but for instance, when miami gets haslem back, i assume they will close with him at the 5. kg can handle him. i think he can handle noah too. and gasol. and STAT (sorta). we basically cant use that lineup of green at the 4 and kg at the 5 when bynum, howard, dampier are in the game.
