The Big Ten returned seven of its top 10 rushers from the 2012 season, so it seemed likely that familiar names would fill this year's rushing chart. It hasn't worked out like that.
Only two players ranked in last year's top 10 -- Nebraska's Ameer Abdullah and Iowa's Mark Weisman -- are among the league's current top 10 ground gainers. The list features five backs who didn't enter the season as starters but have stepped up for injured teammates or simply because they were the best options. Today's poll question asks: Which Big Ten running back has been the biggest surprise so far this season?
You won't see Wisconsin's Melvin Gordon on the list because we don't consider his success surprising at all.
Here are the candidates, listed alphabetically:
Bill Belton, Penn State (Big Ten rushing rank: 7): Lions fans waiting for Belton to blossom are finally getting their wish. Zach Zwinak led Penn State's rushing attack in 2012 with 1,000 rush yards on 203 carries. But Zwinak's fumbling issues created an opening for Belton, who has cashed in during Big Ten play. Belton recorded the decisive fourth-down run in Penn State's four-overtime win against Michigan, quietly had a nice game against Ohio State and last week went for 201 yards and a touchdown in an overtime win against Illinois, the Lions' first 200-yard rushing performance since Larry Johnson in 2002.
David Cobb, Minnesota (Big Ten rushing rank: 5): The Gophers had every intention of establishing their ground game this season, but they pegged Donnell Kirkwood to do most of the heavy lifting. But an ankle injury in the opener slowed Kirkwood and Cobb, who had only one carry last season as a sophomore, is blossoming in a featured role. He established himself with 125 yards and two touchdowns in a non-league win against San Jose State. During Minnesota's current three-game Big Ten win streak, Cobb has three 100-yard rushing performances and 429 total yards on 80 carries.
Tevin Coleman, Indiana (Big Ten rushing rank: 4): After pushing Stephen Houston throughout the offseason, Coleman has emerged as one of many dangerous weapons on Indiana's offense. He has scored in every game this season, averaged 6.4 yards per carry and 131.6 all-purpose yards per game. Primarily a big-play run threat, Coleman also has contributed as a receiver (18 receptions, 164 yards) and as a kick returner.
Treyvon Green, Northwestern (Big Ten rushing rank: 9): Green has been a bright spot for an injury-plagued and inconsistent Wildcats offense this season. Top back Venric Mark has played only one full game because of injuries, but Green has filled the void with 612 rush yards and eight touchdowns on only 95 carries. Green has three 100-yard rushing efforts, including last Saturday at Nebraska, where he gashed the Huskers for 149 yards and three touchdowns on 19 carries.
Jeremy Langford, Michigan State (Big Ten rushing rank: 6): The Spartans entered the season with a pretty desperate situation at running back. They had moved backup middle linebacker Riley Bullough to the position in spring practice, and seemed likely to use several true freshmen at the position. But Langford took charge Oct. 12 against Indiana, racking up 109 rush yards and three touchdowns. He has eclipsed 100 yards on the ground in each of the past four games, scoring six touchdowns during the span. Along with quarterback Connor Cook and an improved offensive line, Langford is a big reason for the offense's turnaround.
Now it's time to vote. Let us know who is the Big Ten's surprise back.
