How can I improve my fantasy team?

This is a very solid team, but Fitzgerald shouldn't be starting until Max Hall shows something at QB. You'll need to monitor Shiancoe's health during the week - he was injured in the Vikings last game and it isn't clear what his status is right now. You'll want to check the status of your kicker and D against what's available on the FA list periodically. right now Crosby and the Chicago D are #10 at their respective positions (standard Yahoo scoring) - not bad, but you may be able to improve through a simple FA transaction. Your RBs are fine, but I'd rather have additional depth there than a 2nd TE or when Rice comes back, you could drop your 6th WR for another backup. RBs are going through a lot of injuries and that isn't unusual.
