Two problems here. First, no one would give up any value for that contract, and second, the C's need Sheed.
For every lazy play he has in a meaningless game, Sheed has 3 great plays in big games. He has shown in two games now that he is as good, if not better than Perk (which I didn't think was possible) at checking Howard in the post. He has shown that when he is interested, he can dominate offensively in the post.
The problem with Sheed is he is terrible to watch if you are C's fan, because when it is not a big game, he goes on full-out cruise control. However, he has shown that he knows how to flip the switch, and is still a tremendously effective player when he wants to be, making this team as deep as any team in the league.
So while we are going to have 3-4 months of frustration watching him sleepwalk through games, we just have to suck it up, knowing that he is going to be tremendously valuable come playoff time, when we need another big body, who can play defense, and can stretch the defense, if they decide not to cover Perk.
