Sure, I get that point, but I am not convinced there is no roster spot here for Povich or McDermott. Sure, it's hard to see the path for Norby given Henderson, Holliday, Mayo, and Westburg on the infield. And it's hard to find the spot for Stowers with Mullins, Santander and Hays right now and Cowser and Kjerstad both ahead of him.
I also don't know that I agree with the idea of trading away 4 guys just because there is no spot for 1 when you can get away with dealing less value (even if we don't have the spot). Value is value and if you don't have a spot for it, we can always trade that in a different deal for additional pieces, either lower level minor leaguers or relief pitching.
Guys like Norby and Stowers, unfortunately, for them are nothing more than collateral for the team at the moment. Just because I have the money to burn to buy something I want, doesn't mean I should burn it if I can get it (or something comparable) for less.
All that said, it'll be interesting to see what moves we make midseason. We certainly have the pieces for it and it is getting to the point now that holding on to them is starting to hurt their value given their ages (particularly in the case of Stowers).
