Michele Roberts responded to a series of assertions that blamed the NBA's current competitive balance issues on the rejection of cap smoothing by the players leading to the 2016 cap spike.

“Frankly, I have been amused by the chatter suggesting that smoothing — or more accurately the failure to smooth — has now become some folks’ boogeyman de jure,” Roberts said in an email. “While we haven’t yet blamed it for the assassination of MLK, some are now suggesting that it is responsible for all that is presumably wrong with today’s NBA.

“Needless to say, I beg to differ.”

The salary cap, which limits the amount each team can spend on players, is tied directly to league revenue. In 2016, the first year under the new agreement, the salary cap increased by $24 million, to $94 million.

“Under the concept we discussed, the total salaries paid to players in the aggregate each season would not have changed, but smoothing would have allowed for steadier, incremental Cap increases, instead of a one-year spike,” an N.B.A. spokesman, Mike Bass, wrote in an email.

In February 2015, union reps from each team unanimously rejected the proposal from the NBA.

Agreeing to artificially lower the salary cap “offends our core,” Roberts wrote. “It would be quite counterintuitive for the union to ever agree to artificially lower, as opposed to raise, the salary cap. If we ever were to do so, there would have to be a damn good reason, inarguable and uncontroverted. There was no such assurance in place at that time.”

Many players had been preparing for the expected spike to become free agents in 2016.

Roberts explained, instead of artificially depressing the salary cap, the league could have proposed advancing television money into 2015 and increasing spending. But it didn’t want to “in part because teams weren’t expecting an early Cap increase,” Roberts wrote.

“Just the same way that they shouldn’t be faulted for seeking to meet teams’ expectations,” she added, “folks should recognize how important we felt it was to meet the reciprocal expectations felt by the players.”

Roberts believes the teams who signed players to bad deals should be blamed.

“I get that there are folks who believe that some of the contracts executed post the smoothing rejection were too large,” she wrote. “I vehemently disagree as I am sure do the players that negotiated those contracts. However, if that’s the beef folks have, take it up with the GMs that negotiated them. The argument that we gave teams too much money to play with is preposterous.”
