The conventional wisdom favors the Cardinals. They pummeled the rest of the division throughout the second half of '09. They resigned Matt Holiday. They still have Pujols, Carpenter, and Wainwright. And nobody in their division got markedly better.
I don't doubt that the Cardinals will be there right to the end and it never surprises me when Tony LaRussa edges a team into the postseason, but the Cardinals are not as complete as some would have you believe. The backend of the rotation is an utter mystery, as Dave Duncan will be expected to work his magic once again with the likes of Brad Penny and Kyle Lohse. Even if he does, if injury befalls one of the Cardinal Aces, the organization does not have a whole lot of compensatory depth.
The left side of the infield is another major weakness. Brendan Ryan and David Freese can catch it and throw it well enough, but they'll make little to no offensive contribution. Few teams are able to survive by punting at short and third. The good news is that John Mozeliak has provided Tony LaRussa with a pair of his favorite things: utility infielders. Felipe Lopez and Julio Lugo can both play pretty much everywhere and hit a little as well, so LaRussa can mix and match to his heart's content.
As a whole, beyond Pujols and Holliday, the Cardinals lineup looks a little tepid. They really need Ryan Ludwick to regain his 2008 form, or Colby Rasmus to make good on his considerable potential. If that happens, and they stay relatively healthy, the Cards could win the division running away, as many expect. However, those are some sizable "ifs".
