2018 NFL Free Agency: Star rating is out of five. Age listing as of Sept. 1, 2018.
Follow me @walterfootball for updates.
-
Matt Paradis (RFA), C, Broncos. Age: 28. 
Tendered by Broncos (2nd round)
Matt Paradis had a Pro Bowl-caliber 2016 campaign, but regressed this season, probably because he had a hip injury that he recovered from in the spring. Paradis should be able to rebound in 2018 and perform on a high level.
-
John Sullivan, C, Rams. Age: 33.
Re-signed with Rams (2 years)
John Sullivan was once a very skilled center for the Vikings. He was a backup for a while after that for some reason, but the Rams gave him a chance to start, and it paid off. Sullivan had a strong 2017 campaign, but he’s 33 and bound to regress at some point in the next 2-3 years.
-
Weston Richburg, C, Giants. Age: 27.
Signed with 49ers (5 years)
Weston Richburg is a talented center, but it’s scary that he missed most of 2017 with a concussion. He played in just four games with the head injury, which doesn’t bode well for his future.
-
Mike Pouncey, C, Dolphins. Age: 29.
Signed with Chargers
Some might be surprised by this release, but Mike Pouncey hasn’t played well for a while. He was horrible this past season, thanks to failing hips. Pouncey is unquestionably talented, but all of the injuries he has suffered over the years have caused him to regress. There’s a chance he bounces back in 2018, but no team should spend a lot on him because he carries high risk.
-
Travis Swanson, C, Lions. Age: 27.
Signed with Dolphins
Travis Swanson is a skilled center, and if it weren’t for major health concerns, he’d be rated higher. However, he has missed a lot of time with concussions, and it’s fair to wonder how much longer he’ll be able to play.
-
Brett Jones (RFA), C, Giants. Age: 27.
Tendered by Giants (2nd round)
Brett Jones did a solid job in relief of an injured Weston Richburg this past season. He’s passable as a starter, but would ideally be a strong backup.
-
Greg Mancz (RFA), C, Texans. Age: 26.
Tendered by Texans (original round)
Greg Mancz did well as a backup center for Nick Martin in 2016, but didn’t fare nearly as well at guard this past season.
-
Ryan Jensen, C, Ravens. Age: 27.
Signed with Buccaneers (4 years)
Ryan Jensen did a decent job as Baltimore’s starting center in 2017, but he could stand to be upgraded.

- Russell Bodine, C, Bengals. Age: 26. — Signed with Bills
- Wesley Johnson, C, Jets. Age: 27. — Signed with Dolphins
