Adam Gase -
Somehow the Gase and Gregg Williams tandem actually somewhat worked last year. Once Darnold got healthy and the schedule got easier, the Jets were able to go on a mini-run. That will have to carry over into the start of this season however for Gase to save his job. Easier said than done with a brand new O-line and new receivers. Not to mention the defense that once again will be without CJ Mosely and traded away Jamal Adams. The first three games are against top tier defenses - Bills, Niners and Colts. An 0-3 start puts this season in a tailspin in a hurry
Matt Patricia -
In two years, Patricia has won a total of 9 games. Jim Caldwell averaged 9 wins a season in his four years Lions tenure. Patricia is out of excuses if he can't get the Lions to the playoffs in year 3. Bob Quinn likely follows. Luckily for the Lions there first two games are against division rivals that are on the ropes - Bears and Packers. The two games that follow are at Arizona and home against the Saints. An 0-4 start would spell doom in Detroit.
First two that came to mind.
