A lot of Giants fan think Jonathan Sanchez will be 1 of the 3 front line power starter that the Giants will throw out there in a couple(as soon as next year) years along with Matt Cain and Tim Lincecum(T-Cum
). Now there's risk with any pitching prospect but I really like him a lot. Dustin McGowan looks like a lost cause and could probably be dropped for Sanchez.
As to Carmona, I don't trust him too much. You should probably wait for one of his advocate to come here and argue for his case. As to who the 2nd drop would be. The Royals fan in me says that Mike MacDougal will eventually blow up Jeremy Affeldt style soon. But now that he's with another team, this might not happen and he's been effective.
