Language in new coaches' contracts hints at possible NFL work stoppage in 2021

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.

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.

That language is also expected to appear in some player contracts being negotiated in free agency; in the third year of those deals, the current collective bargaining agreement is due to expire.
