|Sims took advantage of his lone season at West Virginia in 2013 by averaging 91.3 yards rushing to finish third in the Big 12. He transferred to the Mountaineers after playing three seasons in his hometown for Houston, earning first-team Conference USA honors as a sophomore in 2011 with 821 yards on 110 carries as well as second-team honors the next year with 851 rushing yards and 11 touchdowns on the ground. He was also Conference USA freshman of the year in 2009 with 698 yards rushing before sitting out the 2010 season since he was declared ineligible by the NCAA for reasons that remain unknown. It doesn't seem that he was ineligible for academic reasons since Sims earned an extra year of eligibility at West Virginia after he graduated in four years at Houston. He shined at the Senior Bowl, earning raves for his running and pass-catching abilities and being named as the event's top running back by former Browns general manager Phil Savage. Sims then turned in some decent efforts at the NFL combine to solidify his stock. His 4.48-second 40-yard dash ranked sixth in his position group, and a 126-inch broad jump placed him in a tie for fourth. Sims needs work on his pass-blocking skills in order to develop into a starter in the NFL and must prove he can stay healthy after injuries dogged him with the Cougars.
