A few of the top players from the 2011 class remain with their teams headed toward the 2015 season, but most have either graduated, transferred or headed to the NFL.

Almost four years to the day after members of the 2011 class signed with their respective teams, we take a look at how the top running backs panned out.

SEC SPIN

The SEC claimed three of the top 10 running backs of the 2011 class, according to the 247Sports Composite rankings, none of whom contributed much to their respective teams. (All three transferred.)

But both Auburn’s Tre Mason (2013) and Mississippi State’s Josh Robinson (2014) played in integral part in one of the best seasons in school history.

Mason was perfect for coach Gus Malzahn’s system, powerfully effective alongside Nick Marshall. The same with Robinson, a bowling-ball runner who teamed with Dak Prescott to give defenders all sorts of things to worry about.

Overall, this represents a relatively weak class of running backs for the SEC, which usually produces players like Todd Gurley every year, but there are a few others who contributed — perhaps LSU’s Terrence Magee and Kenny Hilliard most significantly. Both backs served as steady bit players in the Tigers’ backfield.

Others: FB Brandon Wilds, South Carolina; Shon Carson, South Carolina; Mitchell Hester, Vanderbilt; Devrin Young, Tennessee; Dee Hart, Alabama; Jerron Seymour, Vanderbilt; Josh Clemons, Kentucky; Kody Walker, Arkansas; Tom Smith, Tennessee; Marcus Caffey, Kentucky; Marlin Lane, Tennessee.

BIGGEST BUST

There are a few deserving candidates, but we’re giving this one to Brent Calloway because of the train wreck quality. AL.com recently did a story on the 2011 Alabama class and had this to say about Calloway:

Perhaps no recruit had more headlines than Calloway. A longtime Alabama commit, he switched to Auburn a few weeks before signing day. He ultimately signed with the Tide, but never played up to the expectations. Calloway worked with the running backs and tight ends. He played in 13 games in 2012 and made eight tackles, but was dismissed from the team in the spring of 2013 after his arrest for the fraudulent use of a credit card. Calloway played briefly at Arizona Western College that fall and made a cameo appearance on a cable TV show “Necessary Roughness.” Last fall, he gave French professional rugby a try.

OVERACHIEVER

Jay Ajayi, Josh Robinson and David Cobb all have arguments, but we’re going with the one-hit wonder Kapri Bibbs of Colorado State.

Ranked 85th out of 173 running backs in the 2011 class, he was 5-foot-10 and 200 pounds soaking wet. The Plainfield, Ill., native couldn’t qualify academically, so he attended Snow College in ’11 and Front Range Community College in ’12.

He seemed like a pretty unlikely candidate to do anything special at that point, but then-Rams coach Jim McElwain turned him into a superstar in the Mountain West. In 2013, Bibbs became just the third player ever to rush for more than 30 touchdowns in a single season, joining Barry Sanders and Montee Ball (Navy quarterback Keenan Reynolds also managed the feat).

Bibbs ran for 1,741 yards on 6.2 yards per carry, entered the NFL draft early and has spent time on the Denver Broncos practice squad.

RE-GRADING THE TOP 10

2011 No. 1: Isaiah Crowell, Georgia
New No. 1: Melvin Gordon, Wisconsin

Crowell managed a strong college career and performed well as an NFL rookie in 2014, but he spent two of his three collegiate years at Alabama State after getting arrested on a felony weapons charge.

Gordon rushed for 4,915 career yards, putting him 26th all-time and in a cluster with all-time greats like Herschel Walker, Darren Sproles, Michael Turner, Ray Rice and Thurman Thomas. His 2014 season — 2,587 rushing yards, 153 receiving yards, 32 total touchdowns — was the second-greatest every by a college running back.

2011 No. 2: Brandon Williams, Oklahoma
New No. 2:Ka’Deem Carey, Arizona

Williams transferred to Texas A&M, reportedly to be closer to his daughter, but saw very limited playing time at either school.

Carey led the nation in rushing in 2012 (1,929 yards) and finished second in 2013 (1,885 yards), catching a combined 62 passes during the two years as a consensus two-year All-American.

2011 No. 3: Malcolm Brown, Texas
New No. 3: Bishop Sankey, Washington

A slightly lesser version of Carey in college, Sankey strung together two outstanding seasons in the Pac-12 before turning pro before the 2015 NFL draft.

Brown had a pretty ordinary career at Texas and never produced a 1,000-yard season, but at least he played all four years.

2011 No. 4: De’Anthony Thomas, Oregon
New No. 4: Jay Ajayi, Boise State

Ajayi contributed more than 4,500 yards of total offense and 55 touchdowns for the Broncos, including an outstanding 2014 with nearly 2,400 yards and 32 touchdowns from scrimmage. He’s going to be one of the first running backs taken in the draft behind Gordon and Todd Gurley.

2011 No. 5: James Wilder, Florida State
New No. 5: Tre Mason, Auburn

Mason played his best football on the biggest stage for the Tigers, propelling Auburn to an SEC championship in 2013 and doing his part in a national championship loss to Florida State. He ran for an impressive 2,818 yards and 31 touchdowns in his final two seasons combined.

Wilder barely rushed for 1,000 yards in three seasons, but was effective in limited time and made the Cincinnati Bengals practice squad as an undrafted free agent.

2011 No. 6: Savon Huggins, Rutgers
New No. 6:De’Anthony Thomas, Oregon

Keep in mind these are Thomas’ stats as a true freshman(!): 595 yards on 10.8 yards per carry, 605 receiving yards on 13.2 yards per reception, nearly 1,000 yards on 36 kickoff returns and 18 total touchdowns. Though Thomas never made a giant progression — who would after that initial foray — he remained a three-year all-purpose threat as dangerous as any in the country.

After rushing for barely 800 yards in three years, Huggins missed the 2014 season and will transfer.

2011 No. 7: Aaron Green, Nebraska
New No. 7: David Cobb, Minnesota

Green got little playing time before eventually transferring to TCU, where he gained more than 1,000 yards from scrimmage in 2014 as a junior.

Cobb was an everyman for the Golden Gophers, overshadowed in what was probably the best single-season group of Big Ten running backs ever. But he rushed for more than 2,800 yards the last two seasons at better than 5.1 yards per carry.

2011 No. 8: Mike Blakely, Florida
New No. 8: Javorius Allen, USC

Blakely is on his fourth school and has rushed for less than 200 yards during his career.

Allen managed more than 1,900 yards of total offense in 2014, his best college season by far, before heading to the NFL draft. He averaged 5.5 yards per carry for the Trojans and was effective as a receiver.

2011 No. 9: Brent Calloway, Alabama
New No. 9: John White, Utah

White played just two seasons for the Utes, claiming 2,560 rushing yards and 23 touchdowns before turning pro. He still holds the school’s single-season rushing record.

2011 No. 10: Devonta Freeman, Florida State
New No. 10: Josh Robinson, Mississippi State

Robinson barely edged out Freeman for our final spot. Though Freeman ran for more yards (2,255 to 1,997), Robinson was more efficient (6.2 to 5.6 yards per carry), was slightly more dangerous as a receiver and had the strongest single season (2014).

Just missed: Kapri Bibbs, Colorado State; Devonta Freeman, Florida State
