4. The Cardinals. Year in and year out, these guys are best judged over 12 months, not just the offseason. But Beltran leaves a hole in the middle of the order that the addition of Peter Bourjos won't offset, and Peralta arrives with questions about whether he'll be the same guy after his Biogenesis suspension.
