先說結論，今天這球在FIBA有違例，但在NBA不會。
關於回場違例，NBA是這麼規定的：
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.
一旦球員在前場擁有球權，他不可以回到後場，也不可以講球傳給後場的隊友。
但注意，有一個特殊規定
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.
在比賽第四節以及延長賽的最後兩分鍾階段，球員在任意半場接住球並建立有效球權之前
，不區分前場和後場。
所以康利球被點掉後（未接住球）把球撥給Gasol是沒有違例的。
