As CSNPhilly.com reported first, and our Adam Schefter has confirmed, the Philadelphia Eagles have selected Cleveland Browns linebackers coach Billy Davis as their new defensive coordinator. The Eagles have yet to confirm the hire (or any of the other coaching staff hires new head coach Chip Kelly has made), but Davis ran a 3-4 defense when he was coordinator in Arizona in 2010-11. He was also defensive coordinator for the 49ers in 2005-06.
It's not exactly an inspirational hire, especially given how long it took, but Cleveland's defense was pretty good last year and Davis does have experience overseeing an NFL defense. It does seem to indicate a desire by Kelly to switch the Eagles to a 3-4 defensive alignment, and if that is what happens then Davis has one of the most important jobs in the Eagles organization over the next two years. Philadelphia's personnel does not appear to translate fluidly from a 4-3 to a 3-4, so tough decisions will have to be made about who can handle it, who can't and what other pieces will be necessary to augment those in place.
Much more to come on this in the coming days and weeks as the Eagles' plans take shape, but you now know the identity of the man who will lead the defense under Kelly.
