For a WC spot, I'd stand pat, too.
For the division, tough to say. I still wouldn't give up the farm, but I'd be open to moving pieces as long as the return was more than one season of value (like Hamels).
We should strive to be the Cardinals. Make the playoffs every year. I don't want to make any short-term moves. Hamels would be the only one with long-term implications, so I'd bend a little if he were involved, but for a two month rental, forget it.
