The team looks pretty good. Your obvious weakness is SP. You don't really have a dominant #1 guy. If/when Chipper is 3B eligible, he'd be great trade material to try to pick up another starter. Then you could move Lane or Winn into the OF.
You may need some bullpen help at some point - JoBo will start the season on the DL, so try to pick up another closer (Adams, Affeldt, Ryan, Hawkins). If none are available, grab a good set-up guy (Gonzalez, Otsuka) who could always help in WHIP, pick up garbage wins, and extra SOs.
Feel free to take a look at my teams. Any advice helps!
