Silver sent a memo to teams: The integrity of the competition on playing court is cornerstone of NBA
The topic of the memo was the so-called tanking

NBA commissioner Adam Silver sent a memo to the 30 franchise last February 21.
The topic was tanking.
Per USA Today, Over the past several seasons, discussions about so-called 'tanking' in the NBA have occurred with some frequency, both in the public discourse and within our league, and you as governors have taken steps to address the underlying incentive issues by adopting changes to our draft lottery system that will go into effect next year,” Silver wrote in the letter which was obtained by USA TODAY Sports. “Throughout this period, we have been careful to distinguish between efforts teams may make to rebuild their rosters, including through personnel changes over the course of several seasons, and circumstances in which players or coaches on the floor take steps to lose games.
“The former can be a legitimate strategy to construct a successful team within the confines of league rules; the latter — which we have not found and hope never to see in the NBA — has no place in our game. If we ever received evidence that players or coaches were attempting to lose or otherwise taking steps to cause any game to result otherwise than on its competitive merits, that conduct would be met with the swiftest and harshest response possible from the league office.”
“The integrity of the competition on the playing court is the cornerstone of our league,” he wrote. “It is our pact with the fans and with each other, the fundamental reason we exist as a preeminent sporting organization, the very product that we sell. With everything else changing around us, it is the one thing in our league that can never change. We must do everything in our power to protect the actual and perceived integrity of the game.
