Saints interviewed Eagles OC Kellen Moore [ 2nd interview completed on Jan 27 in Philly]

Dude was a starting QB in college, won the most games of any college QB, and took Boise State to the Fiesta Bowl back when stuff like that didn't happen. He was also a backup QB in the NFL for several years fairly recently so he understands the dynamics of NFL rosters. I don't know if he's a Tomlin level leader, but he has to be some kind of leader to do that. He's also a coaches son so I'm sure he understands the importance of leadership.
I hope he is the guy, he's been earning his skin in the game for a few years and this could be the perfect union.
