The running joke in Arizona was that Brenda Warner and Haley's wife were jealous of the amount of time their husbands spent together.
Haley is a no-nonsense dude. And, like Belichick, he grew up in the game. Pulled this from his Steelers' bio: "Haley is the son of Dick Haley, former Director of Player Personnel for the Pittsburgh Steelers (1971-91). As a youth, Haley was a ball boy for the Steelers and attended Steelers training camps with his father. Alongside his father, Haley would watch the Steelers' game and practice film."
They can do worse than Haley. A lot worse.
