Fitz production is all based on how the QB play is. IMO, it might be a little early to start guessing what his numbers would be like. Arizona needs a lot of help on the offensive side of the ball, especially at O-Line. If they can sure up that O-Line and not get Kolb killed (if he even remains the starting QB) then Fitz could be a solid WR1 again. I can say this though, I don't expect him to finish inside the top 5 in fantasy points: Those spots belong to Calvin, Marshall, Julio, AJ Green, and DThomas (in no order).
A win next week and all is forgotten.
