Eagles defensive coordinator Juan Castillo insists his group of linebackers will be ready to play this season. Philadelphia has added a number of impact players this offseason, but they have yet to sign a veteran linebacker. Meanwhile, they allowed Stewart Bradley to leave via free agency. They'll rely on Akeem Jordan, Jamar Chaney, Casey Matthews and Moise Fokou. "They're young kids that they drafted. It takes time to develop kids," Castillo said. "It's a process, and it's our job to develop the kids and make them better. I'm responsible and I have to do a better job, and they'll continue to get better just because we're doing the right things. We're doing the right fundamentals, and it takes time. "The linebackers will be ready to win the Super Bowl," Castillo added. "Remember, it takes 16 weeks, and then really whoever is playing their best during the playoffs. So when you look at it, there's time to develop. You can say that there's not, but the key is, who's playing or fundamentally who's the best come Week 8, 9, 10 -– and during that crunch time. And over the years we've been pretty good during that time, and we'll continue to do that. The young kids will get better just because they're working the proper fundamentals."
