The cap floor is the minimum amount teams must spend on player compensation over a defined period. Teams that fall below the floor must pay the difference directly to players.
While the salary cap ceiling gets most of the attention, the cap floor is equally important for player welfare. The NFL's Collective Bargaining Agreement requires that each team spend at least 89% of the salary cap in cash spending over a four-year rolling period. This prevents wealthy owners from pocketing revenue-sharing money while fielding bargain-basement rosters. If a team fails to meet the floor over the defined period, they must distribute the shortfall directly to their players. The cap floor was introduced in the 2011 CBA and has been a point of contention in labor negotiations. From the players' perspective, it ensures that league revenue growth translates into actual player compensation, not just higher cap numbers that teams hoard as unused space. From the teams' perspective, it adds a spending obligation that can sometimes force less-than-ideal roster decisions, particularly for rebuilding teams that would prefer to stockpile future cap space. In practice, most NFL teams comfortably exceed the cap floor because competitive pressure drives spending. However, teams in deep rebuilds, like the 2023 Arizona Cardinals, can come close to the floor. These teams often sign veterans to short-term deals or give out large signing bonuses (which count as cash spending) to meet the minimum requirement. The cap floor effectively ensures that even the most rebuilding-focused teams still invest in veteran talent.
The 2023 Arizona Cardinals, deep in a rebuild after trading away several stars, navigated close to the cap floor before signing several veterans to short-term deals to meet spending minimums.
