Epstein has talked a lot about scouring for assets. My interpretation is they aren't going to be cutting anybody who has a chance to contribute. Colvin isn't a valuable asset, but he is an asset, and could contribute. Dewitt is similar, especially with the team letting Ramirez go. They probably need to handle 2B and 3B with quantity at the moment and he would be a part of that. James Russel is somebody who is an asset when the team isn't mindlessly trying to use him as a starter. On the other hand, Coleman is kind of useless. If you aren't a legit starter, and don't offer some sort of stand out skill for the bullpen like Russel does with lefties, you probably aren't worth keeping around with the numbers they have, or will have after acquiring a starter.
