Can teams find loopholes in the CBA and make trades that were never intended to be allowed?
The CBA has a general prohibition on circumvention which states that the rules exist to preserve the benefit derived by the teams and players, and that nobody shall do anything to defeat or circumvent the intent of the agreement. The league can use this prohibition to disallow a trade that they feel circumvents the CBA, even though that trade is not specifically prohibited by the agreement.
