Eagles' Chris Polk wants to push for snaps

The projected starting backfield of LeSean McCoy and Darren Sproles is as formidable as any duo in the NFL.

Chris Polk understands that fact.

Polk’s challenge in training camp will be to prove he deserves plenty of snaps with the Philadelphia Eagles this season.

Last season, Polk had 11 carries. He scored three touchdowns.

Talk about production.

Players report to training camp on Friday with the first practice scheduled for Saturday.

Just like 2013, Polk will continue to learn every single day.

"Just overall knowledge of the position, whether it's being patient between runs, knowing the blocking schemes, knowing who to pick up on the blitz, just learning how to read the defense, determining where you're going to cut," Polk told the Allentown (Pa.) Morning Call. "Sell them the store, you know? Even though you know the right A gap is open, don't just run there because they're going to close it when you get there. Just sell it, you know? It's something I can learn from watching Darren and Shady."

Polk had offseason shoulder surgery and will also be competing against Matthew Tucker and undrafted rookie Henry Josey, among others.

Depth charts are not decided during organized team activities. But when training camp opens, it’s serious business.

"We are just trying to get reps and get plays and we are not game-planning anybody," coach Chip Kelly recently told reporters. "That's the fortunate thing for us, is let's see how much work we can get done, get everybody on film and then when we start to get into the season, we'll start to see how we can deploy our personnel in appropriate manners to win games."
