The structure of new NFL coaches’ contracts may be suggesting at a possible work stoppage for the league in 2021.

There have been plenty of new coaching hires this offseason, as teams around the NFL are trying to make the hire that will help lead their franchise to a Super Bowl.

However, it’s the specifics within the new contracts that could point towards a potential disruption once the calendar hits 2021.

From ESPN NFL insider Adam Schefter:

Recent coaching hirings have shined a light on an ugly prospect: that the NFL is starting to set up its fight for a potential work stoppage in 2021 and a disruption of football that season, league sources told ESPN.

In coaching contracts negotiated in the past week, teams are addressing how much each coach would make — or lose — in the event of a work stoppage, according to sources.

Schefter also went on to discuss the fact that there seems to be a somewhat high level of confidence in this actually happening:

One league source told ESPN that he thought both teams and coaches are confident that there will be some type of disruption, and one of the first signs of it is showing up in the language of coaches’ contracts.

Obviously, this is a few years away and may not wind up being a big deal.

But it’s clear that there are at least concerns in place that could causes some issues once the 2021 season arrives.
