A variety of experience runs deep in this grouping that includes three players from NFC North squads: Detroit's Tahir Whitehead and Chicago's Prince Amukamara and Josh Sitton.
Five of the players in this group — Whitehead, Amukamara, Sitton, Brent Grimes and Josh McCown — have appeared in at least 83 regular-season games. McCown is the oldest but has been more active in the past few seasons than earlier in his career.
41. LB Tahir Whitehead, Lions
93 career games; 55 starts; 299 tackles; four interceptions; 3.0 sacks; 19 passes defensed; two forced fumbles
A fifth-round pick in 2012, Whitehead has appeared in all but three games in six seasons for the Lions. He became a starter in 2014 and helped Detroit rank second in the NFL in yards allowed and third in points against. Whitehead started nine games the following season and has totaled 242 tackles in the past two seasons (started all 31 games played).
42. CB Brent Grimes, Buccaneers
135 career games; 119 starts; 527 tackles; 33 interceptions; three defensive touchdowns; 134 passes defensed; three forced fumbles; two fumble recoveries
Initially signed as an undrafted free agent by Green Bay and waived with an injury settlement in 2006, Grimes began a productive and prolonged career on Atlanta's practice squad. He missed the initial roster in 2007 but was signed to the Falcons practice squad during the season. After six years with Atlanta that included one Pro Bowl, Grimes turned in three consecutive Pro Bowl seasons with Miami. Grimes totaled seven interceptions and started all 29 games he played for Tampa Bay the past two seasons.
43. WR Paul Richardson, Seahawks
47 career games; 19 starts; 95 receptions for 1,302 yards (13.7 yards per reception) and eight touchdowns
Richardson, a second-round pick in 2014 (45th overall), did most of his statistical damage in 2017 with his first opportunity to be a full-time starter. The field stretcher posted 44 receptions for 703 yards (16.0 yards per reception) and six touchdowns, but his catch percentage of 55.0 was a career-low.
44. CB Morris Claiborne, Jets
62 career games; 58 starts; 194 tackles; five interceptions; one defensive touchdown; 34 passes defensed; one forced fumble; four fumble recoveries
The sixth overall pick of the 2012 NFL Draft by Dallas, Claiborne moved on from the Cowboys last offseason and landed with the Jets in free agency. Claiborne started all 15 games for the second time in his career and tied his career high of eight passes defensed in 2017.
45. WR Marqise Lee, Jaguars
53 career games; 29 starts; 171 receptions for 2,166 yards (12.7 yards per catch) and eight touchdowns; 15 rushes for 99 yards
Selected six spots before Seattle tabbed Richardson in 2014, Lee has played 30 games the past two seasons, totaling 119 of his receptions, 1,553 yards and six scores after a disappointing 2015.
46. OL Ryan Jensen, Ravens
35 career games; 25 started
The Ravens turned to Jensen to be their starting center in 2017 after he spent three seasons as a sub.
47. CB Prince Amukamara, Bears
83 career games; 69 started; 357 tackles; seven interceptions; 58 passes defensed; three forced fumbles; three fumble recoveries
After spending his first five seasons with the Giants as their first-round pick in 2011, Amukamara has had consecutive one-year deals in Jacksonville and Chicago. His production at both stops were nearly carbon copies:
Jaguars — 14 games, 12 starts, 49 tackles, six passes defensed
Bears — 14 games, 12 starts; 48 tackles; seven passes defensed
48. QB Josh McCown, Jets
95 career games; 73 starts; 23-50-0 as a starter; 1,521-of-2,518 passing (60.4 percent); 17,168 yards; 97 touchdowns; 78 interceptions; 80.8 passer rating; 228 sacks
McCown, who will turn 39 on July 4, has started 35 games with three different teams in the past four seasons (Buccaneers, Browns and Jets). In 2017, his first with the Jets, McCown had career highs in completions (267), completion percentage (67.3), yards (2,926) and passing touchdowns (18). He also took 39 sacks, which was one fewer than he did from 2006 through 2012 when he was primarily a backup QB for the Lions, Raiders, Panthers and Bears.
49. LB Preston Brown, Bills
64 career games; 62 starts; 505 tackles; three interceptions; one defensive touchdown; 1.0 sack; 10 passes defensed; two forced fumbles; four fumble recoveries
Brown recorded a career-best 144 tackles in 2017, which tied for the league lead, according to NFL statistics.
50. G Josh Sitton, Bears
147 career games; 137 starts
Sitton played in 121 of 128 possible games in eight seasons in Green Bay (2008-15), and he missed just two games after becoming a starter in 2009. He made three Pro Bowls with the Packers and another with the Bears after the 2016 season.
