I appreciate his moxy and his effort on the field. He's definitely got the brains to play QB in this league. Sadly, his arm strength and accuracy are grave concerns.
The greatest benefit of Fitzpatrick on this roster, however, is how he will make a great mentor to transition the young QB the Bills eventually take in the draft. A young, physically-gifted QB will learn more from Fitzpatrick than any QB coach will be able to teach him.
