The salary cap for the 15-16 season could be as much as $2 million higher than initial projections.
The revenue numbers upon which the cap is based came in healthier than anticipated.
Teams have been operating on an estimated cap of $67.1 million for the 2015-16 season, but the National Basketball Players Association revealed at the annual agents' summit in Los Angeles this week that the actual cap is expected to come in at least $1 million higher, and perhaps as much as $2 million higher.
The official number won't be set until July 8th when the NBA audits will be completed.
The luxury-tax threshold, projected to be $81.6 million for the coming season, also is expected to be pegged at a significantly higher number, sources said.
