This is a zero tolerance league, and coaches, assistants and coordinators all over the NFL are getting fired, hired and moved all around the place.
It's not just black Monday when Week 17 concludes that these guys have to worry about.
In Dallas, specifically, the franchise is making moves after a disappointing 2017 campaign that saw them ousted early from postseason contention.
Wide receivers coach Derek Dooley has already been let go to begin the month of January, and following him will be another offensive coach.
O-line coach Frank Pollack started with the team as an assistant in 2013 after coming over from the Oakland Raiders the previous year.
It's hard to pin a lot of blame on him after a season where stud running back Ezekiel Elliott was forced to miss six games late in the season to serve a looming suspension and his top lineman, Tyron Smith, also missed multiple games in 2017 before finally being placed on IR late December.
But the most notable strikes against him have to be in Weeks 9 and 10 when Dak Prescott was sacked an insane 12 times, including eight against the Atlanta Falcons during that two-week span.
It was a big step back for the entire Cowboys offense, so the team is deciding to start fresh underneath head coach Jason Garrett in order to get back to that dominant form they displayed in 2016.
