先说结论，今天这球在FIBA有违例，但在NBA不会。
关于回场违例，NBA是这么规定的：
Once a player establishes position in his frontcourt, he cannot move into his
backcourt, nor may he pass the ball to a teammate positioned in the backcourt.
一旦球员在前场拥有球权，他不可以回到后场，也不可以讲球传给后场的队友。
但注意，有一个特殊规定
During throw-ins in the last 2 minutes of the 4th quarter and overtime periods
, frontcourt or backcourt status is not attained until a player with the ball
has established a positive positionin either half.
在比赛第四节以及延长赛的最后两分钟阶段，球员在任意半场接住球并建立有效球权之前
，不区分前场和后场。
所以康利球被点掉后（未接住球）把球拨给Gasol是没有违例的。
