Byron Marshall will be the Pac-12's leading returning rusher in 2014.
Arizona State: The torch was passed from Marion Grice to D.J. Foster toward the end of last season, and Foster will have a full offseason to prepare to be the No. 1 guy. He showed impressive flashes in spot playing time in the past two seasons, and ran for 318 yards (6.2 yards per carry) in three starts after Grice was lost to injury.
California: Much was made about Brendan Bigelow's talent during his career in Berkeley, but it never materialized the way many expected it would. He was beaten out by true freshman Khalfani Muhammad a year ago, then opted out of his final year of eligibility for a shot at the NFL -- and subsequently was not invited to the combine. Getting a feel for how coach Sonny Dykes would like to use his running backs is tough considering the lopsided nature of most of the games last year, but Muhammad showed all the signs that he would develop into a good Pac-12 running back.
Colorado:Christian Powell and Michael Adkins II will both be back after combining for 1,097 yards rushing in 2013. With receiver Paul Richardson off to the NFL, there's the need for added production on offense, and while coach Mike MacIntyre showed at San Jose State he'd prefer that to come through the air, it could add up to more opportunities for Powell and Adkins.
Oregon: Does it even matter who the Ducks hand the ball to? Sometimes it doesn't seem like it, but, regardless, Oregon remains loaded with speed and talent at running back. Byron Marshall (1,038 yards rushing) and Thomas Tyner (711 yards) will both see plenty of carries when quarterback Marcus Mariota (715 yards) isn't running on his own. The team does lose De'Anthony Thomas, who opted to leave early for the NFL, but Thomas turned into a relative afterthought last season anyway.
Oregon State: It shouldn't be hard to improve the Beavers' running game after they ranked 115th in the country in rushing yards per game last season. Their top two backs -- Terron Ward and Storm Woods -- return and figure to see more use under new offensive coordinator John Garrett. There was a glimpse of what could be against Boise State in the Sheraton Hawai'i Bowl as the Beavers unleashed a more balanced approach. Woods ran for 107 yards on 16 carries and Ward added 54 yards on nine carries in a comfortable 38-23 victory.
Stanford:The Cardinal's running back situation is outlined here in more detail, but it should be noted that the competition between Remound Wright, Barry J. Sanders and Ricky Seale -- competing to replace Tyler Gaffney -- will also include Kelsey Young. Young was recruited to Stanford to play running back, but was switched to receiver and is now back at running back. Sanders has the name recognition, but all signs point to Wright getting the first crack at being the primary back. However it plays out, it would be a complete shock if one back was used as much as Gaffney was in 2013 and Stepfan Taylor the two seasons before that.
UCLA: If things play out the way UCLA coach Jim Mora hopes they will, linebacker Myles Jack will be just that … a linebacker. After winning Pac-12 Offensive and Defensive Freshman of the Year, the Bruins would ideally keep him on defense. For that to happen, someone needs to step up. That conversation still includes Jordon James and Paul Perkins, while Craig Lee, a four-star recruit who redshirted last year, also factors into the equation.
Buck Allen will likely head up USC's running back committee next season.
USC: After watching Bishop Sankey turn into one of the nation's premier backs under the tutelage of new coach Steve Sarkisian, USC's deep stable of running backs has to be intrigued. The Trojans will return four of their top five leading rushers from a year ago -- Javorius "Buck" Allen, Tre Madden, Justin Davis, Ty Isaac -- when they were predominantly a run-first team. Allen, who was named the team MVP in 2013, figures to get the first crack at being the starter, but that could be just in name only as a running-back-by-committee scenario seems likely.
Utah: Another season, another new offensive coordinator for the Utes. This time it's Dave Christensen's job to invoke life in the Utah offense, which will return leading rusher Bubba Poole (607 yards) and Lucky Radley (284 yards). The Utes averaged just 4.1 yards a carry as a team last year, which is partially to blame for the change from Dennis Erickson to Christensen after just one year.
Washington: The NFL combine taught us that Bishop Sankey might have been the most physically gifted running back in the country last year. It's not as simple as plugging in another guy to replace him, but the Huskies are still in good shape. Senior Jesse Callier (48 carries, 213 yards in 2013), who was slated to be the starter before an ACL tear in the season opener in 2012, is intriguing and will compete with fellow senior Deontae Cooper (43 carries, 270 yards) and sophomore Dwayne Washington (27 carries, 332 yards).
Washington State: Considering quarterback Connor Halliday had three single-game passing totals that were more than leading rusher Marcus Mason ran for in entire season (429), any discussion about the Cougars' running game is tough to take seriously. Yes, there will still be running backs on the roster. No, they probably won't combine to run for 1,000 yards as a team.
