Reserve RBs battling for roster spot

Depth is always a concern at any position.

For the Philadelphia Eagles, running back is one spot where they seem to have plenty of backups.

LeSean McCoy led the NFL in rushing last season with 1,607 yards.

The Eagles traded for Darren Sproles, who is very versatile coming out of the backfield. Then there’s Chris Polk and Matthew Tucker, a pair of young running backs with loads of potential.

Behind them are the likes of Henry Josey and David Fluellen.

The competition has been fierce thus far in training camp.

“They have to understand … if you're going to be down the depth chart at the running back spot, it's your contributions on special teams (that could make the difference),” coach Chip Kelly told reporters. “So we'll see where those guys fit in on that standpoint.”

Tucker gained experience last season through OTAs and training camp.

“It was new to me,” Tucker told the Wilmington (Del.) News Journal. “That was the big thing for me, not to mess up. I (was) trying to blend in, watch everybody as they go.”

Josey suffered a gruesome injury at Missouri when he tore his ACL, MCL and patellar tendon toward the end of the 2011 season. He also had nerve damage and spent countless hours, weeks and months rehabbing to eventually sign with the Eagles as an undrafted rookie free agent.

“It's a blessing just to be able to go out there and step on the field with these guys at this level,” Josey said. “I think about that a lot. I'm kind of like, 'Wow. I'm still moving forward.' That's the biggest part, to keep moving forward, keep fighting each day.”

Fluellen, who was a standout at Toledo, has also been impressive in battling for a coveted roster spot.

“It's just learning how to practice,” Fluellen said. “When I say that, I mean everything is full speed, and thinking when you're tired. That's the biggest adjustment. … I felt like everybody's battling and pushing each other to get better because everybody wants a spot. You really get a lot of reps in practice, and you also get a lot of mental reps when the other guys are in. So when you go in, everything is just clockwork.”
