I think Glenn could potentially be a good HC. That doesn't mean he WILL BE. We've seen many players work their way up coaching, to flounder when they take over the HC job. It's happening to Jerod Mayo and Antonio Pierce right now.
But Glenn definitely deserves a shot and could surprise many couch coaches like us.
Many may disagree with me here, but I fully believe Brees would make an excellent GM, to the likings of John Lynch.
