Dude is just on vacation after a ridiculously challenging season. He's not running away from a "rebuild" because Brees retired last season...that's the last thing a person like him would do.
Also, fans have always lamented how loyal Payton is. How he keeps players and personnel beyond their usefulness. I seriously doubt he’d leave the Saints high and dry w/out any notice or succession plan despite them sticking w/him through the thickest of thins. Payton has a loyalty to the people in the front office, the fans and city of NOLA.
I firmly believe Payton would do all he could to ensure this organization remains competitive after his departure. He cares about his legacy.
Sean may not coach after this current contract, but I doubt he’s done right now.
