Offense seems nicely balanced. Maybe a little lacking in power, but nothing to sweat about at this point. Your starting pitchers seem a little weak, though. After the top two, it seems like you have a pretty big drop-off. Oswalt shouldn't be counted on for more than a #4, IMO, and ideally he's your #5. Not sure who's on your FA pile, but I'd be most concerned by your SP's. And your SB's seem to be completely dependent upon Bourn. If he doesn't perform like last year, you might have some trouble there too.
