3. Gabe Davis, WR
This last one is tough because, if the Bills are going to compete for a Super Bowl this year, they're going to need the best version of Gabe Davis that they've seen yet; a version they have been hoping for, for quite some time now.
But, Davis is in the last year of his contract, and the question still remains as to whether or not Buffalo will re-sign him after the season. So far, Davis has been highly inconsistent and a hit-or-miss type of player on a weekly basis. Some games, Davis explodes and looks every bit of a legitimate WR2 for this offense.
Other games, Davis gets lost in the shuffle, in essence.
He's had a great training camp and has looked good in preseason thus far, which should give the Bills hope that he can finally bust loose this season. However, at the same time, they could attempt to dangle him as a trade piece for another contending team if they think they'll be able to survive without him.
The offense should be using a whole lot more two tight end sets with the addition of Dalton Kincaid, who will function more like a receiver than a true tight end. If the Bills can get something substantial for Davis, they should explore the possibility.
