Overall, you look pretty solid and have a nice balance. Your OF has a bit of room for improvement, but with Carl Crawford eventually able to slot in there, that could be remedied assuming last year was an aberration and not the beginning of a downward spiral. I find Wieters to be a bit overvalued at catcher, but there certainly won't be anyone better on waivers, and the asking price for those better than him is usually too high from my experience with trying to trade for a catcher.
Your pitching is interesting. I think I may be alone in this, but Dan Haren worries me this year. I can't place my finger on why, but I've had that feeling and avoided him in all of my drafts. Kennedy is a stud. Josh Johnson is hit or miss but has good value based on where he's been getting drafted. Kuroda has huge upside...we'll just have to see if the experts are right about how huge of an impact he'll have with New York. I'm pretty big on Pirates pitching this year, as value tends to be there with none of the starters being selected in many leagues. Hanrahan tends to be their only pitcher drafted and I think he'll be solid once again. He'll blow a few, but the Pirates' low-scoring ways will give him TONS of save opportunities.
Overall, I think you look strong. Injuries to your team could be devastating, as you don't have an overly strong bench, but if that's the biggest thing that can be complained about, you're doing well for yourself. I don't think any moves are necessary right now and I'd stay put for now and see where it takes you. 8.5/10 overall.
Best of luck! Here's my interesting, experimental team: viewtopic.php?t=443587
