Eagles head coach Andy Reid confirmed today that he will not fire defensive coordinator Juan Castillo, a day after the Eagles’ defense struggled again and the Eagles lost their fourth straight game. That’s not exactly a surprise, but it will come as a disappointment to a growing number of Eagles fans who think Castillo is to blame for the team’s lousy start.

Those fans may be interested, however, to learn that Castillo agrees with them: He thinks he’s to blame, too.

“It’s my responsibility,” Castillo said. “We have the answers.”

So what are the answers? Castillo said his players need to get better at tackling and stop making mistakes, like the crucial offside penalty on fourth-and-1 that gave the Bills a first down and allowed them to run out the clock.

“Right now we have to stop that because we have no room for error,” Castillo said. “We’re getting better, but the thing is we have to win.”

And that’s the thing the Eagles haven’t done in four weeks.
