The 5-11, 190-pounder could be an interesting late-round possibility. Crowell was named SEC Freshman of the Year in 2011 after rushing for 850 yards and five touchdowns at Georgia. But he was arrested the following summer on weapon charges. Although the charges were dropped, he was dismissed from the team. Crowell averaged 1,000 yards and 15 touchdowns on the ground over the last two seasons at Alabama State.

James White, Wisconsin.
The 5-9, 200-pounder was extremely productive in college, rushing for 4,015 yards and 45 touchdowns in four seasons with the Badgers. The All-Big Ten second team member is projected to be a fifth or sixth round pick.

Marion Grice, Arizona State.
Before suffering a leg injury at the end of the season, Grice was one of the most productive runners in college football. Even with missing three games, Grice rushed for over 1,400 yards and totaled 20 touchdowns (14 rushing, 6 receiving). He's considered to be an exceptional pass-catcher.

Andre Williams, Boston College.
The 2013 Doak Walker winner and Heisman Trophy finalist is a punishing runner who rushed for over 200 yards on five occasions in 2013. He suffered a shoulder injury late in the season, causing him to withdraw from the Senior Bowl.

Storm Johnson, Central Florida.
Johnson transferred to UCF after playing one season at Miami. During the 2013 season, his only as a full-time starter, Johnson totaled 1,139 yards and 14 touchdowns on 213 carries. He rushed for 124 yards and three TDs in UCF's upset win over Baylor in the Fiesta Bowl.

Terrance West, Towson.
Because this isn't the strongest class of running backs, West chose to enter the draft after his junior season. West dominated his FCS competition, rushing for an impressive 2,509 yards and scoring 42 touchdowns.

Lache Seastrunk, Baylor.
Seastrunk is only 5-9 and he struggled against some of Baylor's top competition, rushing for 59 yards against Kansas State and 19 yards against Oklahoma. But overall, he's one of the top backs in this class and he'd be a steal in the later rounds.
Devonta Freeman, Florida State.
One of the most underrated running backs in this class. Freeman was the leading rusher for the national champion Seminoles in 2013. He rushed 173 times for 1,016 yards and became FSU's first 1,000-yard rusher since Warrick Dunn.

Charles Sims, West Virginia.
A good all-around back that rushed for over 1,000 yards and caught 45 passes for 401 yards as a senior at West Virginia. Sims' first three years of college ball were spent at the University of Houston.

Jeremy Hill, LSU.
Hill rushed for 1,401 yards and 16 touchdowns during his sophomore season with the Tigers. The knock on Hill is that he's been arrested twice, once for hitting a man outside a bar and the other time for misdemeanor carnal knowledge of a juvenile. If Hill, who was LSU's leading rusher in 2012 (755 yards, 12 touchdowns), can prove to the Cowboys that he has matured, his talent could certainly be used immediately.
