Some day-after thoughts on Juan Castillo becoming the Eagles' defensive coordinator:
*When I think of Juan, I think of hard work, at the most basic level -- put your hands here, step that way, bend your knees. I see a technician, not a strategist. A mechanic, not a design engineer. Maybe I don't have the whole picture. The Eagles limit media access to assistants who aren't coordinators; I've talked more with Juan about his son Greg's play at Iowa than about anything involving the Eagles. But I can't help but wonder if Andy Reid, who isn't all that interested in defense, underestimates the complexities of defensive scheming.
*This looks like a desperate move, but it wasn't. Plenty of well-qualified, exciting people were available. This didn't happen because somebody somewhere turned the Eagles down. They wanted to do this. It's interesting that they didn't want to do it enough to announce it, say, the day after they fired Sean McDermott; I think they had some respect for how crazy, insular and arrogant the move would seem. They wanted to do some interviews, get a feel for outside thinking about their defense. But in the end, they did what they wanted to do. Still not sure why they let it be known unofficially that they would interview somebody from the Super Bowl staffs, then didn't bother. They had to announce Juan this week? Why?
*In the end, Juan is a guy who isn't going to demand a lot of changes in the way the Eagles do things, like some guy from the Steelers or Packers might. This is very much about Andy Reid's comfort level, and his control. If things go bad, nobody is going to clamor for Juan Castillo to take over the head coaching job, the way they might if a higher-profile candidate had been hired to run the defense.
