Probably a little late with this post, but I can't help pointing out a couple of interesting developments lately.
The Astros already added some guys...
We already posted something that discusses the additions of Josh Reddick and Brian McCann. My take, briefly, is that both were left-handed hitters with a higher likelihood of solid 2-4 WAR seasons than the Astros that they replaced - Colby Rasmus and Jason Castro, respectively. However, with increasing age comes risk - both of the decline-in-performance type, and in the sudden-catastrophic-injury type. But the Astros managed to add two lefty veterans without losing any draft picks and top-10 prospects, so that is definitely something.
