In the wake of one of the biggest NBA free agency ever, the league’s Board of Governors has decided to unanimously pass new rules that would prevent teams from tampering.

As part of the new and stricter anti-tampering policy, the league will do a random audit on five teams — particularly looking at their communications with other’s front offices, players and agents. However, some NBA teams are reportedly concerned about this move by Adam Silver, according to Adrian Wojnarowski of ESPN.

In conversations with numerous league officials, team owners, general managers and agents, some uncertainty was expressed about the means the NBA might use to investigate alleged rules violations. Atop those concerns for team officials is what league sources insist was commissioner Adam Silver’s toughest decision in bringing new rules to a vote: an annual, random auditing of five teams’ communications with rival front offices and player agents.

Some teams believe that the league is rushing the process of changing the rules.

This new audit rule seems to be a response to recent criticisms about the league’s ability to stop tampering, especially since several deals with free agents were already completed and announced immediately after free agency began on July 1st.

Silver said that some of the punishments for those who will be found guilty of violating the new rules are suspension, fines and loss of draft picks.

Back in July, ESPN reported that a meeting between NBA owners and league officials got heated as they discussed that teams disregard the rules. But now that the amendments have been approved, hopefully, these concerns by team executives will be addressed next.
