The NFL has long liked Gus Bradley and the work he has supposedly been doing to rebuild the Jacksonville Jaguars. The product on the field hasn’t matched the work, but he’s still been well respected around the league.
Firing him midseason would taint that legacy (even with the abysmal win-loss record) and poison a lot of good will that owner Shad Khan has built up around the Jaguars in his first few years as owner. Instability like that of the Cleveland Browns sends out an odor that keeps top talent away both in the players ranks and in the coaching ranks.
