Pat Kirwan thinks Aaron Glenn will be next Saints head coach

Not an exciting pick. As DC for four years, he's only ran a good defense there for two of em. The other two, they were among the worst defenses in the league.

But it doesn't mean he couldn't make a great NFL Head Coach either.
Yeah, I mean Sean Payton got playcalling duties taken away from him when he was the Giants' OC. Just b/c someone isn't a great coordinator every season doesn't mean they can't be a good coach.
