I agree with most of what you're saying but the Twins aren't going to compete in 2012 and I think it's going to be really difficult to compete in 2013. Ryan definitely shouldn't give Span away but to some teams, he could be the difference between the playoffs and sitting at home. He's on the right side of 30, plays up-the-middle, is under a team-friendly contract for a few more years and is generally regarded as an above-average player. That should be able to net a top 100 prospect without much difficulty, top 50 if the team is anxious to compete. The closer the player is to the majors, the lower on the top 100 scale he is likely to be in a deal for Span. But other than Span, there isn't much worth trading. Obviously you take what you can get for Capps, Doumit, Pavano, etc. but it's going to be hard to get much of anything for those guys (but Doumit might bring back a middling prospect).
