One key positional battle for each NFC East team as training camps get underway.
Dallas Cowboys: No. 2 tight end
The Cowboys used a second-round pick on tight end Gavin Escobar, even though starting tight end Jason Witten isn't going anywhere, and they liked what James Hanna showed as a receiver during his 2012 rookie season. They also signed veteran Dante Rosario and continue to look out for a more blocking-oriented tight end. What this all means is that the Cowboys would like to use more two-tight end sets in 2013 (and presumably beyond), largely eliminating the fullback position from their offense and offering quarterback Tony Romo a greater variety of options in the passing game. Training camp will help reveal the depth chart and the ways in which these guys all can expect to be used. Was Escobar drafted because they liked his ability to do something specific? Can Hanna hold him off for reps? How does Rosario factor into the mix? Change is afoot in the Cowboys' offense, and the tight end position is a big part of it.
New York Giants: Starting running back
David Wilson, their first-round pick from the 2012 draft, emerged as an electrifying kick returner in his rookie season and flashed big-play ability out of the backfield. He is the odds-on favorite to seize the starting running back role following the team's release of Ahmad Bradshaw. But, as is often the case, things aren't that simple. The Giants liked Andre Brown a lot as a goal-line back last season and used him a couple of times as a starter, with some success. He's back, and he doesn't intend to hand the job to Wilson without a fight. The Giants' backfield depth chart also includes veteran Ryan Torain, third-year fan favorite Da'Rel Scott and rookie Michael Cox. And these are the Giants, remember -- a pass-first offensive team that needs its running backs to pick up the blitz and help keep Eli Manning safe. Wilson offers the most upside as a runner, but it's entirely possible he could lose the starting job to a better blocker during this camp.
Philadelphia Eagles: Starting quarterback
What else is there? This is the big story of the Eagles' camp and will be one of the big stories in the NFL for the next month. Veteran Michael Vick has the experience, the foot speed and the arm strength, but new coach Chip Kelly wants a quarterback who can avoid turnovers, get rid of the ball quickly and make good, fast decisions in tight spots. These have not been Vick's strengths, which is likely why he faces a challenge from second-year quarterback Nick Foles and maybe even rookie Matt Barkley or veteran backup Dennis Dixon. Vick has to show that he's capable of running Kelly's offense the way Kelly wants it run -- and that he won't revert to his career-long tendencies to try to extend plays and make something happen with pure athleticism. If he can rein it in and operate the offense efficiently, it's his job. If he can't, one of the younger guys could snatch it from him and cost him his roster spot entirely.
Washington Redskins: No. 2 wide receiver
This would be the "Z" receiver in the Redskins' offense. Pierre Garcon plays the "X" position -- the outside receiver who lines up on the line of scrimmage. Santana Moss likely plays the slot again. The "Z" is the outside receiver opposite Garcon -- the "flanker" who lines up off the line of scrimmage to keep the tight end eligible and motions to different parts of the formation if that's called for. The candidates here are Leonard Hankerson, Josh Morgan and Aldrick Robinson. Morgan is the most polished and well rounded of this group, but he has trouble staying healthy. Hankerson is the one the coaches believe has the most upside, but he hasn't been able to develop consistency in his game. If he could, he'd be a valuable piece, because the Redskins believe they can use him in the slot as well. Robinson showed a lot of potential as a favored deep threat last season for Robert Griffin III, but he also has a lot to learn before he's a complete enough player to be used reliably here. Watch to see if Hankerson shows drastic Year 3 improvement in camp. If he does, it's likely his spot to lose, especially if Morgan is banged up as usual.
