What drives it

The mechanism is availability: whether a team's highest-paid players are on the floor. That link is r = +0.47. Paying stars is not the problem. Payroll concentration, how much of the cap goes to the top, is positively tied to winning at +0.28, because good teams pay their stars. The risk is paying them and then playing without them.
