Not really.......Look, Kellen only had 1 year left on his contract. Unless Jerry was willing to extend him another 2 years, it's no surprise he'd wanna seek another OC job ( especially with so many avail ) for a fresh start AND security for his family. I actually saw this coming a while back doing one of his pressers. He was asked about interviewing for other coaching jobs during the playoffs and answered those will take care of themselves.
Bottom line .......I do believe it was mutual ........both were ready for a fresh start.
Posters trying to say left coz of Dak........that's a long reach, stop.
