PHILADELPHIA -- The Philadelphia Eagles will be a very different team in 2015. Will they be a better team? That's a different question, and it's one that Ron Jaworski can't quite give an affirmative answer for.

Before he was an ESPN analyst, Jaworski was the first quarterback to take the Eagles to the Super Bowl. He still lives in the Philadelphia area and keeps a close eye on his old team. And he still does radio appearances like the one he did this week on ESPN affiliate 97.5 The Fanatic. Speaking with host Mike Missanelli, Jaworski said he had concerns about all the changes made by Eagles coach Chip Kelly.

"I don't think they're a better football team right now than they were when the season ended," Jaworski said. "They're making a lot of moves projecting where this team may be, but I just don't see this team as a better team.

"You could ask me in December and I might say 'Yes, they're a better football team.' I just don't see that right now. I'm a big believer in chemistry, and I believe football is the consummate team game. Eleven players on very single play, working together and understand how each play works, why it was called. There has been a lot of turnover on this team. It takes time to develop that chemistry that is so important, that unity that is so important."

After being granted full control of player personnel decisions by Eagles owner Jeff Lurie, Kelly took a wrecking ball to the roster he worked with for two seasons. He traded away quarterback Nick Foles and running back LeSean McCoy. He released veteran mainstays Trent Cole and Todd Herremans. He let wide receiver Jeremy Maclin, safety Nate Allen and cornerbacks Cary Williams and Bradley Fletcher walk away in free agency.

"That bothers me, just as much as the talent level," Jaworski told Missanelli. "A lot of talent has left this football team. I'm just not going to give the press release saying 'Hey, yeah, I think they're a great football team because they made these trades.' I kind of want to see how this plays out."

Kelly brought in quarterback Sam Bradford, cornerback Byron Maxwell, linebacker Kiko Alonso and running backs DeMarco Murray and Ryan Mathews.

"I think Maxwell's an improvement," Jaworski said. "Alonso certainly is an improvement. Where's the safety? Where's the [second] corner? I want to see the finished defense. We forget, the front seven played really well last year. It was not that defense -- the front seven, I thought they were outstanding for most of the season. It was the secondary that needs to be addressed and I want to see how that plays out."

Kelly's offseason plan has not gone perfectly. He attempted to keep Maclin, but chose not to compete with an offer from Kansas City. Kelly took a run at free-agent safety Devin McCourty, but was unable to land him. That left a hole in the middle of the secondary.

There is still the draft for patching some of the spots left unaddressed. As to Jaworski's other point, it takes the offseason workouts and training camp for a team to come together and develop any kind of chemistry. It is unknown, however, what type of chemistry this group will develop.
