The Cards did win 90 games last year JFTR. Anyway I'm cautiously optimistic. I think they'll be around 90 wins again, but they're far from a shoe-in. Berkman, Molina, Carpenter, and Loshe will all perform worse. Beltran helps the Pujols loss some, but he'll also be worse than last season. Freese and Craig will both hit worse, but they'll both have more at bats. Nick Punto hit .278.388.421 in limited playing time and he's gone.
Jake "Replacement Level" Westbrook will be better, probably canceling out Loshe's decline. Holliday will be a smidge better. We'll have full season's (barring injuries of course) of Craig, Freese, and Furcal, but that still leaves a lot of loss for Wainwright to make up for. We led the NL in runs scored last year and probably will be favorites to do so again, but that pitching staff sure is old.
Overall, I think the talent leaving and the talent replacing is close to a wash. Hopefully!
