BREAKING NEWS: The Philadelphia Eagles announced today that offensive line coach Juan Castillo will become the new Defensive Coordinator. The move comes as a bit of surprise since the Eagles had been looking outside the organization after firing Sean McDermott earlier this offseason. Juan Castillo has been with the team for 16 years and 13 as an offensive line coach. A press conference will be held by Andy Reid at 6:30 pm tonight to make the official announcement.
