I think this shapes up as a pretty solid team. Definitely great power in the lineup, and good speed with Reyes, Kinsler, and Cruz. I don't especially like Rios - so I'd keep him on a short leash if I were you. Average may become an issue, so hope that Lee and Braun can compensate for Reynolds and Kinsler.
Pitching looks solid. Hamels is a big bounce-back candidate. You shouldn't struggle too much in any of the pitching categories.
I don't know about that trade. I really like Lee, and Bay's production could slide in Citi Field. Also hits for mediocre average. Rauch is not exactly a lock to be the MN closer. They also mentioned that Guerrier is in the mix and they may trade for a closer before opening day.
