The NFL has approved the current version of the Collective Bargaining Agreement that is on the table. The NFLPA player representatives approved the proposal to be passed on to the entire union body to vote, which is a process that is expected to take a couple of weeks.
In other words, the league’s 32 teams currently do not know under which rules they will be operating at the start of the new league year on March 18. They should know before then, but it may come within a limited window before the new league year begins.
If the players opt not to accept the terms of the proposal, then things will continue as they currently are, which is under the guidelines of not just the previous CBA, but the terms of the final year of a CBA, which has some nuances to it that don’t exist in other years.
