In response to Hfxsoxnut's comment:
moon you're right of course that they didn't do anything to improve the rotation. My only guess is that they feel that they have to evaluate exactly how good or bad the rotation they have now is. Lester, Buchholz and Lackey all have a lot of x-factor going. Lester in particular-what happened to this guy since Sept/11? I think they're hoping desperately that all the changes will help Lester return to what he was.
Maybe part of the strategy is to start working toward assembling a package of players they can trade for a #1-2 starter.
Obviously I'm trying to put this in a framework where biding time makes sense as a strategy toward upgrading the rotation.
I really like Lester and have not given up on him. He showed signs of turning it around the end of last season, so there is much hope, although less than last year at this time.
That being said, I wonder if KC would have given us Myers for Lester straight up. I know they got Wade Davis along with Shields, but they also gave up more good prospects to get both. Maybe even Lester + Morales. I know that would really be a sign of giving up on 2013, but we'd have looked real good going beyond 2013.
