I disagree. Standing pat is standing pat, not folding the tent. They had some attractive pieces that could have helped other contenders and brought in future talent for the Sox (Beltre), and this would have occurred if they folded the tent. And, while they didn't fold, they didn't go all in either. Given the cards they were holding at the deadline, that doesn't look like an unreasonable way to play it.
I've said it before, but I think it bears stating again, and I'd like to hear your thoughts on the matter, I don't think the current team is one you go all-in with in the trade market. They aren't one piece away from becomming strong favorites, or even viable contenders, IMO. Sure, you've thrown out some cliche remarks about how one addition can turn a team around, but nothing specific. Do you really think this team gets over the hump with one more RP or an OF? Do you give up on the future of someone like Ryan Kalish for a Matt Capps, or someone like him, to improve the chances of this team with its current underperformance and amount of players who will finish the season with bandages on?
