Arizona Cardinals: Veteran RB Rashard Mendenhall is the starter, with rookie RB Andre Ellington as his handcuff. Ellington is also the main passing down back.
Atlanta Falcons: RB Jacquizz Rodgers is the handcuff for starting RB Steven Jackson. Rodgers and Jackson are sharing the passing down job. RB Antone Smith would get in the mix for carries if Jackson or Rodgers couldn’t play.
Baltimore Ravens: Second-year RB Bernard Pierce is the handcuff for starting RB Ray Rice. Rice is also the team’s passing down back.
Buffalo Bills: RB C.J. Spiller started the Week 13-15 games, but RB Fred Jackson saw more snaps in all three games—and significantly more snaps on Week Fifteen. Jackson also was the main passing down back. The two RBs are essentially in a RBBC.
Carolina Panthers: RB DeAngelo Williams is the starter, with RB Jonathan Stewart and FB Mike Tolbert as his handcuffs. Tolbert sees time in short-yardage and often in one-back sets. Williams and Tolbert are the main passing down backs. With Stewart out at least for a few weeks, Tolbert takes over as the handcuff for Williams, which was the case in Week Fifteen.
Chicago Bears: Veteran RB Michael Bush is the handcuff for starting RB Matt Forte. UDFA RB Michael Ford would be the handcuff if Bush or Forte couldn’t play.
Cincinnati Bengals: Rookie RB Giovani Bernard is the handcuff for starting RB BenJarvus Green-Ellis. Bernard is also their primary passing down back, which is why Bernard has been seeing more snaps than Green-Ellis for several games. Should Green-Ellis or Bernard be unable to play, RBs Cedric Peerman and Rex Burkhead would back up the starter.
Cleveland Browns: Veteran RB Willis McGahee had been the main ball carrier in Weeks 13-14, with FB/RB Chris Ogbonnaya and RB Fozzy Whittaker backing him up. But with McGahee inactive in Week 15 due to injury, the coaches decided to take an expanded look at recently signed RB Edwin Baker. Ogbonnaya remains the main passing down back.
Dallas Cowboys: With RB Lance Dunbar out for the rest of the season, rookie RB Joseph Randle has taken over as the handcuff for starting RB DeMarco Murray.
Denver Broncos: Veteran RB Knowshon Moreno is the starter, with rookie RB Montee Ball as his handcuff. Moreno is also the main passing down back. If Moreno couldn’t play, RBs C.J. Anderson and Ronnie Hillman would back up Ball.
Detroit Lions: RB Joique Bell is the handcuff for starting RB Reggie Bush. If Bush couldn’t play, RB Theo Riddick would be in the mix for carries on first and second-downs, which was the case in Week Fourteen.
Green Bay Packers: RB James Starks is the handcuff for starting RB Eddie Lacy. FB John Kuhn and RB Kahlil Bell would be in the mix for touches in back of Starks if Lacy couldn’t play.
Houston Texans: RB Ben Tate is the starter, with UDFA Dennis Johnson as his handcuff. RB Deji Karim would be in the mix for touches if Tae couldn’t play.
Indianapolis Colts: RB Donald Brown took over as the starter in Week Thirteen, with ineffective RB Trent Richardson as his handcuff. The two split touches in Week Fourteen. However, Brown started in Week Fifteen, but Richardson saw significantly more carries.
Jacksonville Jaguars: RB Jordan Todman is the handcuff for starting RB Maurice Jones-Drew. Rookie RB Denard Robinson would be in the mix for touches if MJD couldn’t play, which was the case in Week Fifteen.
Kansas City Chiefs: Rookie RB Knile Davis is the handcuff for starting RB Jamaal Charles. If Charles couldn’t play, RB Cyrus Gray would also be in the mix for carries.
Miami Dolphins: RB Daniel Thomas is the handcuff for starting RB Lamar Miller. Both backs split the passing down role. RBs Mike Gillislee and Marcus Thigpen would back up Thomas if Miller couldn’t play.
Minnesota Vikings: RB Toby Gerhart is the handcuff for starting RB Adrian Peterson. FB/RB Matt Asiata started at RB, with Gerhart and Peterson injured, in Week Fifteen.
New England Patriots: RB Stevan Ridley had been the starter this season, but his continued issues with fumbling cost him that role. He was benched during the Week Twelve game due to his 4th lost fumble this season. And he was inactive in Week Thirteen. RB Shane Vereen started in Week Thirteen, but RB LeGarrette Blount wound up sharing carries with him. RB Brandon Bolden surprisingly didn’t many carries and he was inactive in Week Fourteen. The only RB on the Patriots roster who has a clearly defined role is Vereen, who is the main passing down back. Ridley and Blount shared the non-passing down role in Week Fourteen (Blount started), with Vereen as the clear passing down back. In Week Fifteen, Blount started, with Ridley as the top backup.
New Orleans Saints: Veteran RB Pierre Thomas is considered to be the starter, with RB Mark Ingram as his handcuff. Veteran RB Darren Sproles and Thomas split the passing down role. In Week Fifteen, Sproles and Thomas split the majority of carries and the passing down role. Ingram was a non-factor since the team was down the entire game.
New York Giants: RB Andre Brown is the starter, with veteran RB/FB Peyton Hillis as his handcuff. Brown is also the team’s main passing down back.
New York Jets: RB Chris Ivory has taken over as the main first and second-down back. RB Bilal Powell is the team’s passing down back. Powell saw more touches and playing time in Weeks 12-13 because the team fell behind early. The two RBs split snaps in Week Fifteen, but Ivory was the main ball carrier.
Oakland Raiders: Veteran RB Rashad Jennings is the handcuff for starting RB Darren McFadden. FB Marcel Reece and Jennings split the passing down role in place of the injured McFadden in Weeks 10-12. Jennings started in Week Thirteen since McFadden, who was able to play, wasn’t 100%. Reece started at RB and handled most of the carries in Week Fourteen since Jennings and McFadden couldn’t play. Jennings started the Week Fifteen game and handled most of the carries.
Philadelphia Eagles: RB Bryce Brown had been the handcuff for starting RB LeSean McCoy. However, Brown and Polk split carries behind McCoy in Week Fourteen. In colder weather, Polk becomes more of a factor because he’s a more decisive runner than Brown. And Polk saw most of the snaps in Week Fifteen behind McCoy.
Pittsburgh Steelers: Rookie RB Le’Veon Bell is the starter, with RBs Felix Jones and Jonathan Dwyer as his handcuffs. Dwyer likely would see the most carries, however, if Bell couldn’t play due to his size.
San Diego Chargers: RB Danny Woodhead is the handcuff for starting RB Ryan Mathews. Veteran RB Ronnie Brown would be in the mix for touches if Woodhead or Mathews couldn’t play. Brown and Woodhead split carries after Mathews got hurt during the team’s Week Twelve game.
San Francisco 49ers: RB Kendall Hunter is starting RB Frank Gore’s handcuff. RBs LaMichael James and Anthony Dixon would back up Hunter if Gore couldn’t play. Dixon got a lot of work in the 4th quarter in Week Thirteen with the game out of hand.
Seattle Seahawks: RB Robert Turbin is the handcuff for starting RB Marshawn Lynch. If Lynch couldn’t play, rookie RB Christine Michael would be in the mix for carries in back of Turbin.
St. Louis Rams: Rookie RB Zac Stacy has taken over as the starter, with rookie RB Benny Cunningham as his handcuff. RBs Isaiah Pead and Daryl Richardson would be in the mix for touches if Stacy couldn’t play. Cunningham replaced the injured Stacy in Week Twelve.
Tampa Bay Buccaneers: RB Bobby Rainey has taken over as the starter, with veteran RB/FB Brian Leonard as his handcuff. Rainey and Leonard usually split the passing down role.
Tennessee Titans: RB Shonn Greene is the handcuff for starting RB Chris Johnson. RB/FB Jackie Battle would back up Greene if Johnson can’t play.
Washington Redskins: RB Roy Helu is the handcuff for starting RB Alfred Morris. Helu is also the team’s primary third-down back.
