How does each NFC North team look at running back, and what still needs to be done?
Chicago Bears: If you were drawing up plans for an experienced but diverse backfield, you could do a lot worse than modeling after the Bears. Starter Matt Forte is a shifty off-tackle runner and one of the NFL's top pass-catching running backs, a collection of skills that will fit neatly into new coach Marc Trestman's offense. Forte has caught 267 passes since his career started in 2008, the third-most in the NFL by a running back over that stretch. Backup Michael Bush, meanwhile, is a bigger and stronger inside threat who gives the Bears a better option in short-yardage and goal-line situations. He produced a first down on 24.6 percent of his rushes last season, according to ESPN Stats & Information, the 10th-best percentage in the NFL. As long as Forte and Bush are healthy, the Bears' relatively thin depth behind them is irrelevant.
Detroit Lions: Free-agent acquisition Reggie Bush figures to benefit from opponents' attention on receiver Calvin Johnson to much greater extent than the Lions' backfield did last season. Early indications are the Lions will use Bush similarly to the way the New Orleans Saints did earlier in his career. With the Saints in 2006, Bush caught 88 passes. Training camp should bring competition for the right to be the "thumper" behind Bush. Will it be 2011 second-round draft choice Mikel Leshoure, who looked slow and not very elusive after returning last season from a torn Achilles tendon? (No NFL running back had as many touches as Leshoure without at least one play of at least 20 yards.) Or will it be the lesser-known Joique Bell, who as Pro Football Focus points out, made defenders miss regularly last season. He forced 26 missed tackles in 82 carries and actually averaged more yards after contact (2.99) than Bush did with the Miami Dolphins (2.06).
Green Bay Packers: The team re-made its backfield through the draft after years of transition, throwing the situation into unknown territory. At some point, the Packers will have to thin the herd of a group that includes returnees DuJuan Harris, James Starks, Alex Green and John Kuhn, along with rookies Eddie Lacy and Johnathan Franklin. The competition is wide open, although both Starks and Green have failed when given previous opportunities. Lacy's build and pedigree suggests he has an excellent chance to ultimately win the starting job, but Harris impressed the team late last season and could get the first shot this summer.
Minnesota Vikings: Adrian Peterson. Is there much more to say? Historically, runners who put together a 2,000-yard season tend to fall back the following year. But nothing about Peterson's career suggests he will fit neatly into a trend. He has set a goal of 2,500 yards, and however unrealistic it might be, he has earned the benefit of the doubt. Backup Toby Gerhart is in his fourth and presumably last season as Peterson's understudy. While Gerhart hasn't shown much explosion in short stints in Peterson's place, you would think he'll want to look elsewhere for more carries when his contract expires after this season.
