Eagles fire Juan Castillo

PHILADELPHIA -- Juan Castillo's offense-to-defense coaching experiment backfired in Philadelphia, costing the defensive coordinator his job.

Castillo was fired by Eagles coach Andy Reid on Tuesday and replaced by secondary coach Todd Bowles. It was the first time Reid dismissed a coach midseason in his 14 years in charge.

"I put Juan in this situation and things didn't work out the way I had hoped," Reid said. "I take full responsibility for putting him in that situation."

Before the 2011 season, Reid decided to promote Castillo after 13 seasons as offensive line coach. The move was a stunner. It came after a long search and with new defensive line coach Jim Washburn already in place running a wide-nine scheme that isn't widely used.

Castillo was under the microscope right from the start, with nearly every move he made scrutinized intensely. He seemed overmatched in his first season and the defense struggled as Philadelphia started 4-8. But Castillo's unit showed enough improvement during a season-ending four-game winning streak that he stuck around.

Until now.

"I have to do what I think is right, whether it's with public opinion," Reid said, "or against public opinion."

The move came two days after the defense blew a 10-point lead with 5:18 remaining and lost 26-23 in overtime to Detroit. A week earlier, the defense allowed Pittsburgh to rally for a winning field goal in the final seconds.

On defense, the Eagles are a confusing unit. They suddenly can't seem to get to the quarterback. After leading the NFL with 50 sacks last year, they have only seven this year and none in the past three games. And Philadelphia has the 13th-best points-allowed defense in the NFL (20.8 ppg) despite its opponents having the best average starting field position in the league.

The Eagles (3-3) are on a bye this week, and Reid hinted more changes could be coming. An offense that features several dynamic players is next-to-last in scoring and has turned the ball over in bunches.

"Please understand that offense, defense and special teams right now, we need to get better," Reid said. "I'm going to continue to work through that and it's my responsibility to do that. I'm just bringing this to you because this is what's happened so far. I'm still evaluating."

Does that mean QB Michael Vick may get benched for rookie Nick Foles?

"As I sit here today, Michael's the starting quarterback," Reid said.

That's not much of an endorsement.

Reid doesn't have much job security himself, so he'll likely try anything to win. Team owner Jeffrey Lurie already stated in the preseason that another 8-8 season would be "unacceptable." Lurie even said last year that he considered firing Reid after the team failed to live up to high expectations.

"You fight to win football games as a football team," Reid said. "You try to make your football team the best possible football team they can be. You try to better yourself every day. You want your coaches to better themselves every day. You want your players to do it and you hope you have an influence on helping them become the best they can be. That's my job and that's how I go about doing it."

The Eagles will host the undefeated Atlanta Falcons in Week 8 when they return from their bye. Atlanta cornerback Asante Samuel, who was traded by Philadelphia to the Falcons during the offseason, appeared to take a shot at his former team in a Twitter post Tuesday, in a likely reference to Castillo's firing.

"Sometimes you have to blame yourself. You can't try and always point the figure at someone else," he wrote.

He followed that up with the following tweet: "I'm just saying... Aint no decline over here #riseup"

Samuel returned an interception 79 yards for a touchdown in the Falcons' victory over the Raiders on Sunday.

Castillo was with the Eagles for 18 years, longer than any coach in franchise history.

"One of the tougher things I've had to do," Reid said.

Castillo's defense held the Lions in check for three quarters on Sunday, allowing just a pair of field goals. All-Pro wide receiver Calvin Johnson had one catch for 28 yards and Matthew Stafford was 7-of-21 passing.

But, according to defensive players, the Eagles inexplicably changed their game plan in the fourth quarter. They started blitzing more in an effort to pressure Stafford. Also, cornerback Nnamdi Asomugha didn't shadow Johnson the way he did the first three quarters.

Stafford picked apart the defense, Johnson had a big quarter, and the Lions scored 20 points in the fourth and overtime.

"I was on him most of the game," Asomugha said of covering Johnson. "I think when we got to the fourth quarter, there was a lot more trying to give him a different look."

Reid disputed that assessment a day later, saying that "there wasn't a great change of scheme on what we did in the first three quarters."

Regardless, Castillo is gone.

Castillo joined the Eagles in 1995 as an offensive assistant under coach Ray Rhodes. He was promoted to tight ends coach in 1997 and became offensive line coach in 1998.

Bowles becomes Philadelphia's third defensive coordinator since longtime assistant Jim Johnson died in 2009 following a battle with cancer. Sean McDermott had the job for two seasons and Castillo lasted 22 games.

"I'm very familiar with the personnel," Bowles said. "That's not going to be a problem. Our thing right now is to go over our self-scouting, see what we do well and what we don't do well, and try to minimize the things we don't do well, if not get rid of them all together. Make sure we're playing to each player's strength."

Bowles was 2-1 as the interim head coach for Miami last season. The former Temple star played eight seasons in the NFL as a safety, including seven years with the Washington Redskins. Bowles is in his 13th season as an assistant coach. He began his NFL coaching career with the New York Jets in 2000 as a secondary coach and spent four years in Cleveland, three in Dallas and four with the Dolphins before coming to Philly.

"Well, being a player, you can put yourself in the same situations because you've been in them. So when a guy is coming to you with problems, you can refer back to your playing days," Bowles said. "You don't have to agree with them. You say, 'This is why you're doing this, so this is why they're doing this to you.' It just helps the relationship go a lot better."

Reid wanted to interview Bowles after firing McDermott, but was denied permission by Miami.

"He has a good understanding of the game, not only the secondary but the whole picture," Reid said of Bowles. "He gets it and he understands how to tie it all together. He's detailed with his techniques. He relates well with the players. He's a smart guy and he works hard. Those are normally good qualities to have."

The decision comes at a critical time for the Eagles, who are just one game behind the Super Bowl-champion Giants (4-2) in the NFC East. New York is already 0-2 in the division, including a loss at Philadelphia last month. The bye allows Bowles time to set his strategy and move forward. He has to figure things out quickly, however, because the Eagles host the Atlanta Falcons (6-0) on Oct. 28.

"I don't think there will be a transition period," Reid said. "I'm not looking at that as I'm making this move. He understands it and knows it. I'm not looking for transition periods right now. I'm looking for him to step in and do his job to the best of his ability with the players that he has. I think he has good football players and good coaches around him. I expect us to do better."

If not, Reid could be next to go.
