In the 11 seasons of the tax, it has been applicable in nine seasons, and Cuban has paid up in all of them. Exhaustive, league-wide research of payrolls since the implementation of the tax by Mark Deeks of ShamSports.com reveals that the Mavs have surrendered more than $150 million in luxury tax payments.
The Knicks are the runaway leaders, having shelled out more than $195 million. Both franchises dwarf the other 28 teams. The Portland Trail Blazers rank third at $89 million in luxury tax payments and the Los Angeles Lakers are fourth at $84 million.
The luxury tax has been a dollar-for-dollar penalty on salary that exceeds the tax threshold, which has stood at about $70 million the last few seasons.
Cuban has never minded escalating his payroll by taking back salary in trades to acquire the player or players he deemed necessary to maintain annual success, and it did, resulting in 11 consecutive 50-win seasons, a playoff streak that stands at 12 and a championship in 2011.
The Mavs are expected to have a payroll of about $61 million next season, about $3 million over the salary cap, but $9 million under the luxury tax. The Lakers, with Kobe Bryant due $27.8 million this season and $30 million in 2013-14, take over as the West's kings of the luxury tax.
Overall, the Knicks will be holding onto the league title for a few more years -- at least.
