Kliff Kingsburgh was a long-time college coach before making the jump to the NFL in 2019 to be the Arizona Cardinals head coach. He would be with the Cardinals for four seasons, with his best two years being in 2020 and 2021 as they finished just outside the Top 10 in points scored per game.
It would also be the only two seasons that the Cardinals had Kyler Murray for a full season under center. He has been a popular candidate this offseason after being at USC last year with connections with the Bears, Steelers, and Eagles.
Kellen Moore was offensive coordinator for the Cowboys for four seasons from 2019 to 2022 and in a rare move stayed on the staff after they made a head coaching change from Jason Garrett to Mike McCarthy.
He had success running that Cowboys offense with Dak Prescott under center and would leave this past season to take on a similar position with the Los Angeles Chargers. However, he didn't have the same success as the Chargers finished near the bottom in most statistical categories.
While this past year was probably his worst as a coach, he has enough of a resume from his time with the Cowboys that it would make sense for the Buffalo Bills to consider.
