23. Matt Rhule, Carolina Panthers
As far as I am concerned, Matt Rhule is the worst head coach that is still currently employed. He has to be the early favorite for the first coach fired next season as the Carolina Panthers were a disaster in 2021 after showing some promising signs in 2020. Rhule and the Panthers seriously messed up the quarterback situation and parted ways with a promising offensive coordinator in Joe Brady. That is an awful sign for Rhule and the Panthers.
22. Arthur Smith, Atlanta Falcons
Arthur Smith was touted as an offensive genius with the Tennessee Titans and that genius did not show up with the Atlanta Falcons. Granted, he took one of the worst rosters in the league to a 7-10 record, but Atlanta still ranked third-to-last in DVOA. Smith had a better record than some of the other first-year coaches yet the future doesn't seem as bright.
21. Dan Campbell, Detroit Lions
The Detroit Lions won three games in 2021 yet where the hardest three-win team to beat, maybe in NFL history. That is a testament to Dan Campbell's coaching and once the Lions build up some talent and get a better QB, they could be frisky, especially in a division that is projected to stink next season and beyond.
20. Robert Saleh, New York Jets
Robert Saleh has been described as a leader of men and that is still a fair description of the former San Francisco 49ers defensive coordinator. While the Jets struggled in 2021, they ended the season on a bright note with better play. While they went 1-3 in the last four, they lost to Miami by seven, lost to Tampa Bay by four in a game that they should not have lost and was down by three to the Bills heading into the fourth quarter.
