yeah I can't think of any other good FA signings by this management team. Roark and Anderson could turn out ok (for what they were expected to be) although I guess Anderson was technically a trade. Shaw looks pretty bad right now, but he is not being paid much, and they can non-tender him after the season if they want.
Probably their record right now looks better from the trade front. Consider some of the guys they have acquired via trade (GILES, Grichuk, Hernandez, Hatch, Waquespack, Kay + Woods-Richardson) and what was given up in return. Of course the Happ trade turned out to be s*** but you can't with them all.
