This is what it looks like to me...
The Saints are in cap space hell this offseason. They aren't going to get better, and may in fact get much worse. I feel like Sean Payton doesn't wanna deal with a blown up roster and rebuild at this point in his career. Since he has a few years remaining on his contract, and obviously the Saints don't want to fire him, I think he's going to take a break and wait for a year or two before returning after the Saints clean up the mess. At that point, there may be two options... The saints suck and get a top pick in the draft and Payton returns to draft a QB and be the savior.... or maybe the Saints actually like who they have in place and agree to let Payton go elsewhere.
Either way, I don't think this is it for Payton. I just don't think he wants to deal with the shitstorm that NOLA will be dealing with in the next year or two.
