ESPN first reported the news.
Coughlin had several meetings with the Eagles brass, including a face-to-face meeting scheduled on Thursday.
As talks appeared to be heating up, Coughlin decided he wasn't the proper fit to patrol the Philadelphia sideline.
Per Rapoport, Coughlin is still open to coaching but wants the job to be perfect. He's also open to a potential consulting job with the Giants, among other things.
