Castillo rallied defense with video
To see where the heads of his players were, the workaholic defensive coordinator cued up footage of the bouts between Micky Ward and the late Arturo Gatti, who went toe-to-toe without giving up an inch in a series of epic fights.
Ward's story ultimately was told in The Fighter starring Mark Wahlberg (Vince Papale in Invincible).
I don't think it was a coincidence the Eagles shutdown the Dolphins' vaunted short-yardage running attack after they watched those fighters pound each other yet refuse to give in.
Or that the Eagles dropped the Jets with a torrent of shots unleashed largely by the defense Sunday.
Castillo made his point and so did his players. More on that later.
