Point: Sean McAdam has doubts about the Cards' chances in '06:

Despite moving into a new stadium, the Cards have refused to increase their budget, causing them to lose a number of free agents, including outfielder Reggie Sanders and second baseman Mark Grudzielanek. Larry Bigbie and Junior Spivey, their respective replacements, can hardly be considered upgrades. Starter Matt Morris left for San Francisco, leaving a significant hole in the rotation, and adding Braden Looper to the bullpen may not be such a positive move.

Counterpoint: Adrian Mott at his Baseball Nuggets site "scratches his head" about McAdam's Cards blurb in an entry entitled New Stadium, New Outfield, Same Results and thinks the Redbirds are primed for another first place finish.  

What Mott writes about Spivey is pretty interesting:

Sure, Spivey is a risk at second for the Cardinals, and is not the steady, consistent type of player that Grudzielanek, who seems to run though walls and still hits .300 year after year is. But Spivey has more potential to be an upgrade to Grudzielanek's offensive production and figures to be just that if he can stay healthy.

The entirety of Mott's article is worth the read.  He does an interesting job of breaking down the Cardinals '06 team.
