The Philadelphia Eagles will officially put last season's woeful performance behind them this week.

Rookies, quarterbacks and selected veterans will report for training camp at the NovaCare Complex this afternoon, followed by the rest of the team Friday. The first full-team workout is scheduled for Saturday, when the Eagles can forget about last season's 4-12 debacle and begin focusing on the upcoming season under new coach Chip Kelly.

A new coach, a bunch of new players and a new culture have made the Eagles one of the most interesting teams in the NFL.

Fans are more excited than ever, as evidenced by the more than 200,000 who have acquired free tickets to the team's five open practices at Lincoln Financial Field during camp.

But the Eagles will need to win in order to maintain the hype. They have not won a playoff game since the 2008 season and haven't even reached the postseason since 2010.

Here are some training camp story lines that will help determine if they can make a comeback this season.

Chip Kelly's offense

Kelly lit up scoreboards at the University of Oregon with a high-energy, read-option attack. Several NFL teams - San Francisco, Seattle, Washington - used a similar offense last year with great success, but it remains to be seen if Kelly's version can work at the top level. The speed of the offense will be different. Kelly had the Eagles sprinting through drills and plays during their offseason workouts. The theory is that the more offensive plays the Eagles run, the more opportunities they will have to score.

As usual, everything revolves around the quarterback. Will Kelly go with a more mobile player, such as Michael Vick or Dennis Dixon, or choose a pocket passer, Nick Foles or rookie Matt Barkley?

Billy Davis' defense

The Eagles' defense has been struggling for years since legendary Jim Johnson died after the 2008 season. Sean McDermott, Juan Castillo and Todd Bowles all got shots at being the defensive coordinator without much success.

Davis will be institute a 3-4 base defense for the first time in franchise history. There is a concern about whether they have the necessary personnel to execute the system. Newcomer Isaac Sopoaga is the only proven nose tackle on the roster. Newcomer Connor Barwin is the only experienced outside linebacker. Former defensive ends Trent Cole and Brandon Graham are switching positions.

Dave Fipp's special teams

With former special-teams coordinator Bobby April now with Oakland, Fipp will be in charge of turning around the Eagles' unit after a mediocre performance in 2012.

Place-kicker Alex Henery, long snapper Jon Dorenbos are the only veterans certain to retain their jobs. Damaris Johnson has the inside track on being the punt returner after setting a franchise record with a 98-yard return for a touchdown last season. Free-agent pickup Donnie Jones or rookie Brad Wing will be the punter. Whoever wins that job will likely also serve as Henery's holder.

Wide receiver Arrelious Benn, who was acquired in trade from Tampa Bay, will challenge cornerback Brandon Boykin and running back Bryce Brown to become the kickoff returner.

Rookie safety Earl Wolff should land a spot on the Eagles' coverage units.
