The second apron was sold as a tax. In practice it functions as a hard ceiling, and front offices are now building rosters backwards from it.

Teams above the threshold lose the mid-level exception, cannot aggregate salaries in trades, and see draft picks frozen. Those restrictions bite harder than the dollars.

The mechanics nobody reads

A contending team carrying three maximum contracts has roughly eleven roster spots left and almost no legal way to improve them mid-season.

That forces a specific archetype: cheap, defensively versatile wings on minimum deals, drafted late and developed internally.

The consequences on the floor

Depth is the first casualty. By March, rotations shorten, minutes concentrate, and injury risk rises for exactly the players a title run depends on.

Two executives, speaking independently, described the same internal rule: no contract beyond three years for any player outside the top four of the rotation.

Where this ends

Expect more short, front-loaded deals and more trades executed in July rather than February.

The apron did not reduce spending. It redistributed when and how the spending happens.
