I don't know, my impression is that a fast start could mean the difference between a playoff team, and another year like 2012. This team will get stronger in the middle of the year, and if they're in contention at midseason, I could definitely see them making a move for a front of the rotation starter.
The DL will have 4 contributors on it at the beginning of the season who will have an impact once they return. There is also more depth at the minor league level than we've seen in several years. They all need some polish, but many of them have potential to contribute solid value -- Webster, DLR, Brentz, Bradley, Lavarnway, Iglesias and if we're lucky Bogaertz and Kalish.
