The Chicago Bulls and Brooklyn Nets have a mini-rivalry going after the Bulls managed to upset Brooklyn on their home court in game seven of the first round last year. It's so heated that even two mild-mannered characters in Joe Johnson and Jimmy Butler had a heated moment during the third quarter of Brooklyn and Chicago's game tonight.

It seems as if Johnson attempted to mush Butler with a finger. The All-Star break couldn't have come at a better time for these two teams to cool down.
