The Tools That Disappear
The practical effect is easier to see as an inventory of things a team above a threshold can no longer use. It cannot sign a meaningful free agent using the mid-level exception, which is the primary route for adding a rotation player without matching salary. It cannot serve as the destination in a sign-and-trade, closing off a common path for acquiring a star who is technically a free agent.
In trades it loses the ability to combine several contracts into one larger salary, which is how a team without a single big contract acquires a highly paid player. It loses the ability to take back more money than it sends out, so every deal must be matched closely. It loses the option of using cash to smooth a transaction and the flexibility to pick up a useful veteran from the buyout market late in the season. What remains is minimum-salary signings, the draft and precisely matched trades, which is a thin toolkit for a team whose payroll implies it should be contending.
