It's not hard to find Jacksonville Jaguars observers who expect former Alabama standout T.J. Yeldon to be the NFL team's primary ball-carrier in 2015.

But Yeldon isn't taking that for granted. In his mind, he's a rookie at the bottom of the depth chart.

"I got myself as last, and I'm still trying to work my way up to the top," Yeldon told NFL.com while attending the league's Rookie Symposium this week. "I'm just out there to compete and work my way up to the top, see what I can do. ... I feel like I can be a three-down back, but I'm just out there trying to do what I do. I'm still learning, so I'm not trying to say I'm a three-down back or anything right now. I've done it before at Alabama, but it's a different league now, so we will see."

While perhaps not too impressed with himself, Yeldon has impressed plenty of others during the Jaguars' OTAs and minicamp, which finished last week

"He looks really good in short-area change of direction," Jacksonville middle linebacker Paul Posluszny said of Yeldon. "He looks really, really good there. It's 'How does a guy move in space? How athletic is he?' That's what stands out. With him, he definitely has it."

During their offseason program, the Jaguars have emphasized improving their running game. Last season, they finished 21st in the NFL in rushing offense and most recently had a 1,000-yard rusher in 2011 with Maurice Jones-Drew.

Jacksonville selected Yeldon is the second round of the NFL Draft in May and signed offensive tackle Jermey Parnell from the Dallas Cowboys and center Stefen Wisniewski from the Oakland Raiders as free agents. Third-round draft choice A.J. McCann from South Carolina also might crack the starting lineup in the offensive line at guard.

During his three seasons at Alabama, Yeldon ran for 3,322 yards and 37 touchdowns on 576 carries and caught 46 passes for 494 yards and two touchdowns. On the Crimson Tide's all-time rushing list, Yeldon ranks fifth in carries, fourth in yards and third in touchdowns. Yeldon joined Alabama from Daphne High School, where he was the state's Mr. Football and Class 6A Back of the Year in 2011, a year after helping the Trojans go 15-0 and win the AHSAA 6A title.

Jacksonville's other running backs are Denard Robinson and Storm Johnson from last year's team, waiver-wire pickup Bernard Pierce and undrafted free agent Corey Grant of Auburn. The Jaguars also have Toby Gerhart, but he is expected to assume more of an H-back role this season.

Robinson ran for 582 yards and four touchdowns on 135 carries, Johnson had 86 yards and two touchdowns on 29 rushing attempts and Gerhart gained 326 yards and scored two TDs on 101 rushing attempts in 2014. Pierce ran for 366 yards and two touchdowns on 93 carries for the Baltimore Ravens last season.
