Dave Cameron on the Edwin Jackson signing

Dave Cameron wrote a bit about the Cubs signing of Edwin Jackson. Here's part of it.

But we should note that Edwin Jackson makes them better, and this price for Edwin Jackson is still completely reasonable based on his established performance level. That the Cubs aren’t yet obvious contenders shouldn’t cause us to tell them to stop trying to improve. By bringing in Jackson and Carlos Villanueva today, while already adding Scott Baker and Scott Feldman, the Cubs have now acquired four interesting starting pitchers this winter. They’ve rebuilt their entire rotation, essentially, and have set themselves up to be able to trade Matt Garza — after he proves he’s healthy, anyway — without it creating a huge problem for their Major League team. They did the same drastic overhaul of their rotation that the Twins and Royals went after this winter, just they did it without giving up useful Major League outfielders or top outfield prospects in the process.

I liked the point he made earlier in the article in that just because you're not contending doesn't mean you can't add talent to your roster. The Cubs have money to spend so why not spend some of?
