My realistic view of the Sox right now, July 30, is that now is not the time to make a big trade to improve the rotation as was done o/a August 1, 2013. Why? Because the rotation right now is not that bad: Porcello and Price are both pretty solid; Pomeranz just might be as good as indicated at San Diego this year; Wright can be very good when his knuckler is working; ERod was good last year and could be that way again this year.
But also because this is a pretty talented lineup which, however, lacks experience. I think the Sox can get to the playoffs as currently configured--and assuming the bullpen DL's return in good order--but maybe lacks the maturity to win in the postseason. The Angels (Sciosia, actually) showed us how to deal with Ortiz in game 1 Thursday night--when in doubt, walk him. Detroit should have done that in the ALCS in 2013, and you can bet it will happen this postseason. Everyone else in the lineup is up and own like a yo-yo. Collectively, they have scored a lot of runs and will score a lot more, but collectively they right now are vulnerable to good pitching, not just great pitching. And right now I would define good pitching as anyone with good breaking balls (curve, slider, changeup, knuckle curve, whatever) that is in or close to the strike zone. Even Linecum, whose ERA 8.49 and who walked 6 guys in 5 innings last night, did OK (4 runs in 5 innings)--because he threw a whole lot of breaking balls.
In other words, my advice to Dombrowski is to limit himself to maybe getting another good bullpen arm, period, and let this team work its way through the rest of the season, whatever happens. And by all means don't trade away any more of our top prospects. Enough is enough.
