Juan Castillo, who spent 13 seasons as an Eagles offensive line coach and has been with the organization for 16 years, will switch over to the defensive side of the ball, and replace Sean McDermott, who was fired on Jan. 15. The team, which also added Howard Mudd as the new offensive line coach to replace Castillo, made the announcement on Wednesday.
A former linebacker at Texas A&I (1978-80), Castillo, 51, played for the USFL's San Antonio Gunslingers (1984-85), and also was an assistant at Texas A&M-Kingsville from 1982-85.
Castillo is one of few NFL coaches of Hispanic descent. He is fluent in Spanish and has promoted the NFL product for its Spanish-speaking audience.
"Juan is one of the smartest and most dynamic coaches in the NFL," Carolina Panthers coach Ron Rivera said. "If anyone could cross over to the dark side (of defense), he's the guy. Seriously, if anyone can do it, Juan Castillo is able to do it. I don't know if I have seen anyone any more committed as a coach in this league than him."
Castillo joined the Eagles in 1995 as an offensive assistant under coach Ray Rhodes. He was promoted to tight ends coach in 1997, and then offensive line coach in 1998.
"I have a strong affinity for Juan going back to our days spent together in Philadelphia," Minnesota Vikings coach Leslie Frazier said. "I can remember Jim Johnson and our defensive staff putting our game plans together and we'd always get together with Juan just to make sure they were sound in terms of pressures and blitzes. Sometimes, I felt like he was on our defensive staff. And to do this day, he and I talk every week during the season to talk about other offenses in the league."
Castillo was one of four members of Rhodes' staff to be retained by Reid in 1999.
"Great move by Coach Reid. Juan is a football junkie who has always studied the entire game," said St. Louis Rams coach Steve Spagnuolo, a former Eagles assistant. "He's a detailed, aggressive, and passionate football coach - all attributes vital to coaching defense."
The Eagles won the NFC East this season, but lost to the eventual NFC-champion Green Bay Packers, 21-16, in the wild-card round at Lincoln Financial Field. After the dramatic, come-from-behind, 38-31 win over the New York Giants at The Meadowlands, they finished the year with three consecutive losses, all at home.
McDermott's defense finished 12th overall, giving up 327.2 yards per game.
