Really interesting question... I'd have to get the opinion of a bunch of people smarter than me about when Lincecum's and Cain's arms might be subject to falling off. Some scouts think Lincecum is a walking time bomb. Some think he can throw like that forever. Cain worries me a bit more, simply because he looks like a workhorse, so he's been treated like one. Still, he's not in any imminent danger for this season. Either way, with a rotation that sick, we'd be in pretty good shape. I don't care if we have to sign Pedro Feliz to play third... Wouldn't be a bad idea, his defense is really really good. I'm really not too concerned with our defense right now... Theriot is the only below average defensive player starting for us, and DeRosa is probably the only one that comes in right at average. We probably have the best defensive outfield in the league, Soto has an excellent reputation, and DLee is about as good a first baseman as there is. And Aramis has come around on his defense by quite a bit. He was well above average last year. Still, replace Aramis with Feliz, and with our starting staff consisting of Cain, Lincecum, Z, Hill, and Lilly... We'd probably have the best run prevention in the league. We certainly wouldn't need to score many runs to win most days.
