I love me some Fitz, but quite frankly only a moron in my opinion would vote yes.
Fitz has a well established top end. There is still a glimmer of hope for Manuel to become a good NFL starting QB.
I would however, trade Lewis, Tuel, the Jills, and Spiller (if and only if Whaley/Marrone are convinced they are not going to resign him after this season) to get Fitz as a veteran backup for Manuel. Manuel could learn quite a bit from Fitz and it would really increase Manuels chances of long term success.
