Nothing is wrong with Carmelo wanting to become a free agent.
If he opts out of his contract and wants to be woooed by teams that is his contractual right. If he decides to leave, that is his prerogative and decision. Knicks fans were up in arms when he said he will explore his opportunities after the season, so Melo had to backtrack a bit on his comments.
