Four dozen SEC running backs have rushed for a 1,000 yards in the past decade.

That makes for a lot of unhappy faces when ranking the 10 best. …

10. Marcus Lattimore, South Carolina

South Carolina has had just two 1,000-yard seasons since 2000. Lattimore had one — as a freshman in 2010 — and would have had more had it not been for two devastating knee injuries.

He also ran for 38 career touchdowns and was a weapon out of the backfield, adding 74 career receptions for 767 yards.

9. T.J. Yeldon, Alabama

Yeldon often is overlooked in the Tide’s run of great running backs under Nick Saban, but Yeldon came the closest to producing three consecutive 1,000-yard seasons.

He just missed as a junior, when he gained 979 on 194 carries while splitting the workload with Derrick Henry.

He left Alabama with 3,322 yards and 37 rushing touchdowns.

8. Nick Chubb, Georgia

Chubb took over for Todd Gurley midway through the 2014 season and finished with a flurry.

He ripped off eight consecutive 100-yard games to close the season, including a career-high 266 against Louisville in the Belk Bowl victory.

He finished with 1,547 yards — averaging 7.1 per carry.

He entered his sophomore season as the talk of the SEC and was even better.

He topped 100 yards five consecutive times and was averaging 8.1 yards per carry before his season-ending knee injury against Tennessee.

His rehab going well, all signs point to Chubb making another run at 1,000-plus yards in 2016.

7. Mark Ingram, Alabama

Ingram worked in tandem with Glen Coffee in 2008 and Trent Richardson in 2010, but in 2009, he was a workhorse Heisman Trophy winner and national champion.

Ingram ran 274 times that season for an Alabama-record 1,658 yards. His mark since has been broken, twice, first by Richardson in 2011 and last season by Derrick Henry.

6. Todd Gurley, Georgia

Gurley nearly cracked 1,000 yards in all three of his seasons before leaving early for the NFL.

He opened his Bulldogs career with 1,385 — at the time joining Herschel Walker as the only true freshmen to reach 1,000.

Injuries and an NCAA suspension ended his bid for 1,000 yards each of the next two seasons. He finished with 989 yards as a sophomore and 911 in six games as a junior, when he emerged as a Heisman favorite.

5. Alex Collins, Arkansas

Collins improved every year — and he opened his Razorbacks career with 1,026 yards.

That grew to 1,100 as a sophomore and surged to 1,577 as a featured back this past season.

Collins left after his junior year with 3,703 career rushing yards — second all-time in program history.

4. Tre Mason, Auburn

Mason had back-to-back 1,000-yard seasons in 2012 and 2013, when he led Auburn to the BCS championship game.

He ran for 1,816 yards that final season, breaking Bo Jackson’s Auburn record. It was the SEC’s third-best single-season rushing total at the time.

3. Derrick Henry, Alabama

In 2015, Henry had the greatest single season in SEC history — breaking Herschel Walker’s record, winning the Heisman and leading the Tide to a national championship.

But in Alabama’s share-the-carries system, that was Henry’s lone 1,000-yard season.

Having the best season doesn’t always translate to best career.

2. Darren McFadden, Arkansas

McFadden finished second to Tim Tebow in the 2007 Heisman vote after rushing for 1,830 yards and 16 touchdowns. That total was the second-highest in SEC history — until Henry and Leonard Fournette raced past it in 2015.

McFadden left with 4,590 yards and still ranks second in SEC history.

1. Leonard Fournette, LSU

Fournette, with 2,987 yards, has put himself in position to make a run at Walker’s career SEC rushing record of 5,259 yards.

He ran for 1,953 yards last season — in just 12 games. He led the country in yards per game at 162.75 — almost 15 more than Henry.

Only injury will prevent Fournette from a third consecutive 1,000-yard season in 2016, which he’ll enter as a leading Heisman Trophy candidate.
