Glazer: Schwartz or Spagnuolo
Fox's Jay Glazer reported earlier today that Titans defensive coordinator Jim Schwartz is on a plane right now heading to Detroit for his second interview. Makes sense that the Lions want to talk to him again, and the fact that they would bring him in so soon after Tennessee's playoff loss to Baltimore would seem to suggest they're interested in making a hire quickly (and that it could very well be him).
Glazer said if the Giants beat the Eagles today, I think the Lions make a strong move towards Jim Schwartz as early as this week. If the Giants lose, Glazer said the Lions will bring Giants defensive coordinator Steve Spagnuolo back for a second interview as well and then it could go down to those two guys.
I can't confirm or refute those reports, but I'm chasing them and will share what I know when I know it.
