2018 NFL Free Agency: Star rating is out of five. Age listing as of Sept. 1, 2018.
Follow me @walterfootball for updates.
Chris Boswell (RFA), K, Steelers. Age: 27. Tendered by Steelers (2nd round)
Chris Boswell is one of the NFL's top kickers. He's hit his field goals at a 90 percent or better clip in two of his three seasons, and he's 6-of-8 from 50-plus in his career.
Dan Bailey, K, Cowboys. Age: 30. Signed with Vikings
Dan Bailey has been one of the best kickers in the NFL over the years, minus 2017 when he was injured. Save for 2017, Bailey has never hit worse than 84.4 percent of his field goals.
Matt Bryant, K, Falcons. Age: 43. Re-signed with Falcons
If it wasn't for Adam Vinatieri, we'd all be marveling about how amazing it is that Matt Bryant has been kicking so incredibly well into his 40s. Despite his age, Bryant was 34-of-39 in 2017, including a ridiculous 8-of-9 from 50-plus.
Adam Vinatieri, K, Colts. Age: 45. Re-signed with Colts (1 year)
Adam Vinatieri somehow continues to be one of the top kickers in the NFL despite his age, as he has barely missed any 50-yard field goals over the past several seasons. He's bound to regress soon, but people have been saying that for years.
Caleb Sturgis, K, Eagles. Age: 29. Signed with Chargers
Caleb Sturgis lost his job to Josh Elliott this past season, but not because of anything Sturgis did. Sturgis was a perfect 3-of-3 prior to getting hurt, and he was 35-of-41 in 2016, including 4-of-6 from 50-plus.
Chandler Catanzaro, K, Jets. Age: 27. Signed with Buccaneers
Chandler Catanzaro struggled in his final season with the Cardinals, but rebounded this past year. He drilled about 85 percent of his field goals and hit every extra point. He's 5-of-8 from 50-plus the past two years.
Cairo Santos, K, Rams. Age: 26.
It wasn't Cairo Santos' fault that he lost his job in Kansas City. Harrison Butker was just better. Santos has been an accurate kicker within 50 yards, but he's been inconsistent from long range.
Kai Forbath, K, Vikings. Age: 30.
The good news for Kai Forbath is that in the past two years, he's 47-of-53 (88.7%), including 7-of-10 from 50-plus. The bad news is that he's missed eight extra points in that span.
Ryan Succop, K, Titans. Age: 31. Re-signed with Titans (5 years, $20 million)
Ryan Succop is a pretty average kicker; he was 35-of-42 in 2017 after going 22-of-24 the year before. He's missed two extra points in each of the past three seasons.
Graham Gano, K, Panthers. Age: 31. Re-signed with Panthers (4 years, $17 million; $9 million)
Graham Gano was a near-perfect 29-of-30 in 2017, though that's a bit misleading. He didn't make a single 50-yarder (until the playoffs), and he whiffed on three extra points.
Sebastian Janikowski, K, Raiders. Age: 40. Signed with Seahawks (1 year)
Adam Vinatieri has kicked incredibly well into his mid-40s, so perhaps that's good news for Sebastian Janikowski, who turns 40 in March. The bad news is that he's coming off a back injury that caused him to miss all of 2017, so we'll see if he can continue to be a great kicker.
Cody Parkey, K, Dolphins. Age: 26. Signed with Bears
Cody Parkey doesn't attempt many field goals from long distance, but he hit about 90 percent of his kicks in 2017, while missing just one extra point.
Daniel Carlson, K, Vikings. Age: 23.
Zane Gonzalez, K, Browns. Age: 23.
Blair Walsh, K, Seahawks. Age: 28.
Dustin Hopkins, K, Redskins. Age: 27. -- Re-signed with Redskins
Nick Novak, K, Chargers. Age: 37.
Connor Barth, K, Bears. Age: 32.
Nick Rose, K, Texans. Age: 24.
Sam Ficken, K, Rams. Age: 25.
Marquette King, P, Raiders. Age: 29. Signed with Broncos
Marquette King might be known most for his on-field dancing celebrations, but he's actually one of the top punters in the NFL; he ranked sixth in net average last year. He's also just 29.
Shane Lechler, P, Texans. Age: 42.
Shane Lechler has been one of the greatest punters in NFL history, and he continues to rank among the league leaders in net punting. He turns 42 in August, however, and could decide to retire.
Dustin Colquitt, P, Chiefs. Age: 36. Re-signed with Chiefs (3 years, $7.5 million)
Dustin Colquitt has been ranked between eighth and 15th in net punting average in the past three years.
Kevin Huber, P, Bengals. Age: 33. Re-signed with Bengals (3 years)
Kevin Huber has been in the top 15 of net punting in two of the past three years.
Donnie Jones, P, Eagles. Age: 38. Signed with Chargers
Donnie Jones said he would retire, but has changed his mind. He has ranked sixth, 11th and 16th in net punting over the past three years. He turns 38 this summer, however.
Brad Wing, P, Giants. Age: 27.
Jon Ryan, P, Bills. Age: 36.
Jordan Berry (RFA), P, Steelers. Age: 27.
Pat O'Donnell, P, Bears. Age: 27. -- Re-signed with Bears
