The NBA announced Wednesday that the players' union formally rejected a so-called "cap-smoothing" proposal that would pay players the same 51 percent of basketball-related income they get under the current collective-bargaining agreement, while artificially lowering the cap over several years. The plan was put forth to manage the influx of revenue that is coming with the $24 billion television deal that begins after next season.
NBA teams using internal data are projecting the salary cap to jump to between $88 million and $92 million per team, sources told ESPN. To compare, this season the cap is set at $63 million and next season it is projected to land at about $66 million. To put it into perspective, the largest salary-cap jump in history is $7 million in one season. What happens in 2016 could triple that leap.
Owners have been trying to avoid such a spike because it would dramatically raise salary levels for free agents that season. James, for example, could take his salary from about $22 million next season to around $30 million if he signs for the maximum salary in 2016.
