I was thinking back to this last offseason where we were all excited about what talent we would bring back when we traded our huge surplus of pitching.  We now know that that huge surplus of pitching would turn into somewhat of a deficit of pitching when Noah Lowry went down with an injury that could very well end his career and when Correia when down with that oblique strain and we had nobody to replace him with.  I was thinking that maybe we might be able to actually fully rebuild our team by trading the new huge surplus of pitching we are about to have sometime soon. 

Our current rotation is Lincecum/Cain/Sanchez/Correia/Zito.  On the way up to the majors we have MadBum, Tim Alderson, and Henry Sosa, all of whom will most likely reach the majors at some point.  We also have a bunch of not-as-good prospects like Clayton Tanner, Ben Snyder, Kevin Pucetas, Jesse English, etc.  I think it's safe to assume one of those guys will mature into a servicable starter at some point.  Maybe more than one of them will.  Also, there is a slim chance Lowry might come back from his injury.  But once that happens, how do we get them into the rotation?  If we have 7 or 8 pitchers ready to take a spot in the rotation, we can afford to get ride of a couple to get the younger ones in.  This is a great problem to have because good starters are very valuable and can draw a lot of return in a trade.  That's just the thing a team like the Giants need to help the rebuilding process.  We can use some of our starters to get us some quality hitters, which would round out our team enough to be able to compete again.  But who would we trade?

Lincecum is our ace, and we couldn't afford to lose him, so I would think he's off limits.  Zito and his fatass contract are here to stay whether we like it or not.  Cain is extremely good and could draw a good amount of return, but I'd really hate to see him go.  Sanchez could draw more return than Cain right now because he's been stellar this year, and he still has more potential that he can still fulfill.  Correia has been pretty good as a starter, and he also has more value because he can be used as a reliever.  He wouldn't draw the same amount as any of our big three, but he is definitely the most expendable of our starters (excluding Zito because we can't get rid of him)  Who should we trade later on when our pitching prospects become major league-ready?
