Kenjon Barner is hungry, literally and figuratively.

After spending 2014 on the Eagles' practice squad and getting just 37 offensive touches in a crowded backfield last season, the running back is looking to carve out a bigger role with the Birds in 2016. DeMarco Murray is gone, and with Ryan Mathews and Darren Sproles away from the team earlier this week at practice, it was Barner getting the first-team reps.

Mathews missed Tuesday's practice with an illness, and Sproles hasn't reported to the Eagles' voluntary workouts, which become mandatory from June 7-9.

So Barner, the 27-year-old RB Chip Kelly coached in college and traded for prior to the 2014 season, has had some opportunities to impress new head coach Doug Pederson. And Barner wants to make clear that despite his Oregon ties — he's one of three remaining players from Oregon that Kelly brought to the Eagles, along with Josh Huff and Taylor Hart — he's not only here because of the coach he outlasted.

"It's a great opportunity," Barner said, "just a fresh start. Go out there and continue to show what you can do, continue to make plays and constantly have your name in the coaches' minds.

"For anybody who says, 'Oh, that's Chip Kelly's guy,' no, I'm a football player. I wouldn't be here if I wasn't a football player. I wouldn't have gotten drafted if I wasn't a football player.

"It's not a chip on my shoulder. Yes I went to Oregon, yes I played under Chip, I love Chip to death, but I'm a football player. I create my own lane. I'm not gonna let anybody place me in a box and tell me what I am."

At 5-9/195, Barner doesn't fit perfectly into the box of a classic bell cow back. He's more of a Sproles-lite, a shifty back who can catch passes out of the backfield. He showed that last preseason, when he rushed 13 times for 91 yards and a touchdown and also caught four passes for 72 yards, including a 50-yarder.

That kind of backfield versatility is necessary in the offense Pederson brings over from the Chiefs, the offense Andy Reid ran for many years here. In Kansas City, Pederson and Reid utilized their running backs often in the passing game, just as they did with the Eagles. Even when Jamaal Charles went down for the year after five games last season, that trend continued with Charcandrick West catching 20 passes and DeAnthony Thomas getting some grabs out of the backfield.

"I fit whatever role they want me to fit," Barner said. "Whether it's catching balls out of the backfield or whatever it is. Jamaal Charles is a great back and if I can do half of what he's done throughout his career I'd be lucky."

Barner has patiently waited three years for this kind of opportunity. Mathews and Sproles are expected to be the Eagles' top-two ball-carriers, but both are getting older and neither is an every-down back, Mathews because of all the injuries and Sproles because he's more of a situational matchup nightmare. So even with the addition of fifth-round pick Wendell Smallwood, there should be some opportunities for Barner, who has done all he can to further his own development.

"Just older, more mature, more professional than I've been in the past," Barner said. "Understanding the offense, really going home and studying, really knowing what my responsibility is.

"For me, man, it's just about being mature, growing. I feel like if you're not growing, what are you doing? You constantly have to grow, have to evolve, not only physically but mentally. That's kind of where I'm at.

"I did take it seriously last year, but having the opportunity to go through what I've been through, go home and be with my family, have guys like (Chris) Maragos, I talk to him on a daily basis about football, about life. Sproles constantly being in my ear still — he may not be here but he's still in my ear. It's a lot of things coming together."

One change Barner made this offseason was to his diet. It came from a conversation with the NFL's best all-around running back, Pittsburgh's Le'Veon Bell.

"I had a talk with Le'Veon Bell back in January," Barner said. "I spoke with him and we were just talking about eating. I'm the type of guy that if I see somebody and I see a change in them and I see it's positive, I have no problem telling you, 'I like what you're doing, tell me how you did it.' I reached out to him because I've been seeing pictures of him and I've seen his body change. We came in the draft together and he's always been a big guy, but he hasn't been that cut, that ripped. So I reached out to him like, 'Yo, what did you do, what's your diet, what have you been taking, what are you doing and what are you not doing?' Just really trying to pick his brain.

"I'm trying to be great. And if I see you doing something that's pushing you to the next level I'm gonna ask you how you did it.

"I'm not gonna say I've been perfect. I'm just really big on sweets, I have a sweet tooth like no other and I can thank my dad for that — growing up he always had candy and snacks by his bed so I would always sneak in his room and eat them. That's the hardest thing, that's like my kryptonite."

Sweets weren't a part of the Chip Kelly regimen, that's for sure. But with the coach who brought Barner to the Eagles now in San Francisco, it's more on the players to keep themselves on track, both in the kitchen and with their sleep schedule.

"It's different, a lot slower, obviously," Barner said of practices under Pederson. "Is that good? I mean, you don't get as tired. But you're not in as good of shape as you were in Chip's offense. Chip's offense, you have to be in tip-top shape. So we're still getting there, still certain times when we're tired, times when you shouldn't be tired. So you have to do a lot of the conditioning on your own outside of here.

"Today, [Pederson] asked us who's getting eight hours of sleep. Everybody cares about it because you want your players to be at their best and you can't be at your best if you're not getting enough sleep, (but they're) two completely different people."
