Tight end is a position where the Bills had an entrenched starter in Scott Chandler. However, following Chandler’s ACL knee injury in Week 16, his availability is in doubt for training camp and the start of the regular season. With limited depth behind him, especially in the pass catching department Bills GM Buddy Nix has admitted the team is in the market to make an addition.

The heavy hitters
Jared Cook – Tennessee – Cook has great size and the physical attributes to be a mismatch in coverage similar to Chandler. Athletic enough to be a downfield threat in the passing game, Cook hasn’t been able to produce in a way that’s fitting of his skill set. But there’s no denying his pass catching and big play ability. Age 25.

Fred Davis – Washington – Davis is a versatile tight end, but coming off an Achilles injury his physical state will play a large role in what he could command on the open market. Capable of getting consistent separation in the passing game Davis also has the ability to line up as an H-back or on the line. Age 27.

Tony Gonzalez – Atlanta – He’s 50-50 to retire according to reports and if he does play a 16th season he’s expected to re-sign with the Falcons. Gonzalez has lost a step, but can still find the soft spots in zones and is a go-to guy in the red zone. Age 37.

Dustin Keller – NY Jets – Another mismatch in the passing game, Keller is more of a split out type tight end. A solid route runner with great hands, Keller can be a go-to guy particularly in the red zone. His athletic ability enables him to make plays despite less than ideal size. His injury history (see: hamstring) is the only drawback. Age 28.

Middle market
Martellus Bennett – NY Giants – Bennett is a capable of being an in-line blocker while also athletic enough to make plays in the passing game. Coming off a career-high season in catches (55), receiving yards (626) and touchdowns (5) Bennett is a good mismatch in terms of size and speed. Age 26.

Anthony Fasano – Miami – The veteran tight end is never going to wow anyone with athleticism, but is a well-rounded tight end that has enough athleticism to make plays and help a passing game. Capable of standing his ground as a blocker, Fasano offers an offense a consistent and durable player. Age 28.
