I agree about your offense. I love that you have Salty and McCann both. Personally I am not a big fan of Uggla and have concern about his production this year, but perhaps that comes more from being a Mets fan than a fantasy baseball critic
Also, I know in the past I might have overvalued Carl Crawford. He always looked so good with the potential for great power and speed. This isn't to suggest I don't like him in your OF (I think you have a great OF), but I am wondering if you think there is any chance you might be able to swap Carl for a pitcher from someone in your league who might still think Crawford will put up the numbers he used to be projected for? I dunno, just a passing thought.
I think your pitching does need work, and agree with the other poster you should drop scutaro for an available pitcher. In my 12 team league, I went with Sonnanstine from the FA pool because I am a big fan of his K/BB ratio, think he might be a little undervalued for someone who posted almost 200 innings last year. Just some things to consider... Good luck!
