Billy Davis sat at the head of one of the cafeteria tables inside the NovaCare Complex Monday, surrounded by a swarm of reporters trying to get a feel for one of Chip Kelly’s most curious hires. Certainly his most important.

Eventually, the subject of Davis’ less-than-sizzling resume as defensive coordinator came up. His units ranked 32nd and 26th in his two seasons as DC in San Francisco. In Arizona, his defense finished 20th and 29th in yards. Those are not the most comforting statistics for fans who have little else to go off of.

“In my past I’ve got good stats and I’ve got bad stats, like most people,” said Davis. “There are a lot of reasons for all of it, I’ve got no excuses for any of them. Everywhere I’ve been I have had good people, I’ve learned lessons from those experiences and I think I have gotten better because of it. It’s something I’m bringing to the Eagles now, I’ve got some experience in calling games and working schemes and game-planning and adjusting. At the end of the day we’re problem solvers. You learn from your experience and you move forward.”
