It would help to see your roster, the # of OFers you CAN start, and your league settings.
Personally, I'm high on Markakis, Bruce, Adam Jones and Nelson Cruz. The others are fine, I just like these better.
One piece of advice. I wouldn't rule any guy as 'untouchable'. Any player should be available, for a price.
McClouth is a guy that I would dangle in a trade for a top-end SP. He has great 'name' value based off of last's years break-out. He should net you the most value in return. Pairing him with Lastings Milledge's breakout 'upside value' could bring in some fantastic combination of pitching!
