I thought this might be worth raising.
Let's say Sheed were traded to Phili as part of a deal for Iggy & Delambert -- he's obviously not going to pick up his third year option there. I also think he'd freak, refuse to play for that team and likely would accept a favorable buy out of the remainder of his deal just to take the money -- say, half of his 2010 salary -- and move on. of course he'd then go sign with cleveland or la or someone for the vet to try and exact revenge, but that would probably work in the Cs favor anyway.
It's a thought....
