As JCA said, waiting for January free agents or settling for Lannan is a way better move when we're filling the #5 spot in the rotation behind SS, Gio, JZ, and Ross, rather than filling the #1 spot with Jason Marquis.
Brian Goodwin has shown nothing but promise and athleticism and now he's taking the AFL behind the woodshed. I'm concerned about Bourn - he'll probably be an overpay, since Werth is a far better leadoff hitter which makes Bourn basically a defense/steals-first player. I'd be okay with Harper in CF until Goodwin gets ready (Harper shouldn't be the Hulk for another couple years), keeping LaRoche, and finding a LF for 2-3 years to replace Morse. Groom Moore to replace LaRoche at first.
