The Eagles don't plan to fire coach Andy Reid because they know it would be very difficult to replace him with someone better, according to sources. However, Reid controls his staff and that could lead to trouble down the line. Things could become dicey in Philadelphia is if there's a clash over taking the defensive coordinator title away from Juan Castillo. Reid promoted Castillo from offensive line coach to defensive coordinator before the season, a decision that has been met with harsh criticism as Philadelphia's defense has faltered.
