Last year's playoff series between the Washington Wizards and Bulls saw tensions run high between Nene and Jimmy Butler.
Apparently Nene hasn't gotten over it.
The Washington Wizards are among the elite in the Eastern Conference. But up until Wednesday night they hadn't played like it against fellow contenders on the road.
Tom Thibodeau has been adamant all year that how the Bulls practice is indicative of the way they'll play.
Jimmy Butler said Monday that the Bulls don't back down to anybody.
The Bulls begin their new season with the same team that ended their previous one.
