Pro Football Focus is currently running a series on the "Secret Superstars" of the NFL. Players who performed better than the media or even the numbers said were dubbed as the secret stars of their respective teams. Last week the NFC North was broken down, and Bears Insider John Mullin wrote his story on cornerback Tim Jennings being named the Bears unknown star.
Here is a look at the rest of the division, and who Pro Football Focus named as each team's behind-the-scenes superstar.
Detroit Lions: Willie Young, DE
With all the star power on the Lions' defensive line, Willie Young had to fight to even make a roster spot in 2010. The sixth round draft pick was inactive for all but two games his rookie season, but Turk McBride's off-season departure bumped Young up to the No. 4 defensive end in 2011, behind Kyle Vanden Bosch, Cliff Avril and Lawrence Jackson.
And Young made the most of his time on the field, as PFF notes "of all 4-3 defensive ends with at least 100 pass rushes, Young had the fourth highest Pass Rushing Productivity Rating (13.4)." In other words, Young knows how to get to the quarterback. He recorded 3.0 sacks in 2011, and could be in line for an even bigger role in 2012 alongside defensive tackles Ndamukong Suh and Nick Fairley.
Green Bay Packers: D.J. Smith, ILB
Packers' inside linebacker A.J. Hawk has been one of the few draft busts under Ted Thompson, but the general manager, like the Lions,also may have struck gold in the sixth round.
The 5-foot-11 linebacker was considered undersized coming out of Appalachian State last year, and was assumed to play a role on special teams more than anything defensively for the Packers. With starters Desmond Bishop and Hawk manning the 3-4 defense, the rookie Smith played zero defensive snaps until Week 12 against the Lions on Thanksgiving Day. Including that Week 12 game, Smith recorded 33 tackles and an interception in four consecutive starts.
Thompson and the Packers have been reluctant to part ways with Hawk, but Smith's impressive showing last year could force Green Bay's hand to insert him in the starting lineup.
Minnesota Vikings: Chris Cook, CB
Knee injuries cost the 2010 second round draft pick a decent amount of his rookie season, but Cook came back strong in 2011. PFF noted one play in particular, when Cook broke up a Matthew Stafford pass intended for Calvin Johnson late in the fourth quarter. That contest, which PFF called Cook's "coming out party," saw the second year cornerback allow just three catches on six targets, and two passes defended.
Cook was arrested for domestic assault during the year and was dismissed by the team, but he seems to have his legal troubles behind him. He is expected to enter the season as one of two Vikings' starting cornerbacks, and at 6-foot-2 will be valuable in defending the likes of Calvin Johnson, Jordy Nelson and Brandon Marshall.
