Jay Ajayi

If Ajayi can hold on to the ball (four fumbles in 2013) he should be one of the nation's best. He's a big back at 6-0, 216, but he showed a lot of athleticism in his first year as starter last season, bolting for 1,425 yards and 18 touchdowns on just 249 carries (5.7 YPC) and catching 22 passes for 222 yards and another touchdown. With a promising quarterback (Grant Hedrick) and two impressive receivers (Matt Miller and Shane Williams-Rhodes), the Broncos are poised to score a lot this year, and Ajayi will be their primary touchdown source. He could even improve on his receiving production this season as the senior trio of Geraldo Boldewijn, Aaron Burks and Kirby Moore graduated.
