NFL waiver wire, explained: What is the process, and how does it affect the Patriots?

However, not all 37 transactions will be the same. The NFL has separate protocols for so-called vested veterans and players with less league experience. Veterans immediately enter the open market as free agents after being released, while the latter must pass through the waiver wire, where they can be claimed by another franchise or enter free agency if unclaimed.

What exactly does all of this mean for the Patriots and the NFL's other 31 teams, though? Let's break it down.

Franchises will make their final preparations before the season, with substantial changes being made to league rosters. Players will either be waived or released, but not all will instantly become free agents and be free to sign with any team.
