2014 NFL Free Agent Tracker: Star rating is out of five. Age listing as of Sept. 1, 2014.
Follow me @walterfootball for updates.
Jimmy Graham, TE, Saints. Age: 27. Franchised by Saints
Jimmy Graham is an unstoppable force. He's an athletic beast, and the scary thing is that he's only going to get better over the next couple of seasons as he continues to increase his football IQ.
Dennis Pitta, TE, Ravens. Age: 29. Re-signed with Ravens (5 years)
Think Joe Flacco missed Dennis Pitta for most of the 2013 season? Pitta came back from a hip injury and caught 20 balls for 169 yards and a touchdown in just four games.
Tony Gonzalez, TE, Falcons. Age: 38.
Tony Gonzalez, now 38, signed on with CBS to be one of their analysts, but there's a good chance he'll come out of retirement to play for a contender late in the year (Cris Carter did this with the Dolphins back in 2002). Despite his age, Gonzalez is still a threat over the middle and a strong end-zone target.
Brandon Pettigrew, TE, Lions. Age: 29. Re-signed with Lions (4 years, $16 million)
Brandon Pettigrew has great talent, but he's never been able to live up to his potential. He constantly screws up, whether it's dropping passes, fumbling or missing assignments. Maybe he can put it together on a new team, but time is running out for him.
Brandon Myers, TE, Giants. Age: 28. Signed with Buccaneers (2 years, $4.25 million)
Brandon Myers caught 79 passes in 2012, but was a major disappointment with the Giants. He and Eli Manning just never clicked.
Jermichael Finley, TE, Packers. Age: 27.
Jermichael Finley always had great talent, but could never put it together on the field - until the first half of this past season. He was playing well, but unfortunately suffered a season-ending neck injury. It remains to be seen whether he can be 100 percent again.
Scott Chandler, TE, Bills. Age: 29. Re-signed with Bills (2 years)
Scott Chandler is just an average tight end. His size (6-7, 263) makes him a solid end-zone target.
Fred Davis, TE, Redskins. Age: 28.
Fred Davis has never lived up to his potential because of numerous injuries. His talent might be sapped, but he's only 28, so he's worth a shot at a cheap price.
Kellen Winslow Jr., TE, Jets. Age: 31.
Kellen Winslow played much better than expected this season - despite missing a handful of games - but he's still a shell of his former self.
Dustin Keller, TE, Dolphins. Age: 29.
Dustin Keller should probably be a 1.5-star free agent, but I'll bump him up for the write-up. Keller tore his ACL, MCL and PCL in a preseason game, and if that wasn't enough, he also dislocated his knee. He's going to have a tough time coming back from this injury, so he'll have to sign a short-term "prove it" deal.
Owen Daniels, TE, Texans. Age: 31. Signed with Ravens
Owen Daniels just can't stay healthy. He has missed 26 games in the past five seasons. Given that he turns 32 in November, his career probably won't last much longer.
Garrett Graham, TE, Texans. Age: 28. -- Re-signed with Texans
John Carlson, TE, Vikings. Age: 30. -- Signed with Cardinals (2 years)
Ed Dickson, TE, Ravens. Age: 27. -- Signed with Panthers (1 year)
Andrew Quarless, TE, Packers. Age: 25. -- Re-signed with Packers
Ben Hartsock, TE, Panthers. Age: 34.
Jeff Cumberland, TE, Jets. Age: 27. -- Re-signed with Jets (3 years)
Bear Pascoe, TE, Giants. Age: 28. -- Signed with Falcons
Dante Rosario, TE, Bears. Age: 29. -- Re-signed with Bears
Nate Byham (RFA), TE, Buccaneers. Age: 26.
Alex Smith, TE, Bengals. Age: 32.
David Johnson, TE, Steelers. Age: 27. -- Signed with Chargers (2 years)
