Sean Payton took over a team that went 3-13 and needed a top down overhauling of the roster and coaching staff to a total change in culture from a loser to a winner.
Dennis Allen took over a very talented team with an outstanding winning culture that had bad luck with injuries in 2021. Prior to Brees' retirement, the Saints under Payton made four consecutive playoff appearances, four consecutive NFC South Championships, and before the injury, had Jameis freaking Winston at 5-2 as a starter with 14 TDs to just 3 INTs and very much looked like a team poised to take a fifth consecutive NFC South Championship and playoff appearance before a surreal amount of injuries.
Payton's 13-10 is incomparably different than Allen's 10-13.
