Kwame missed a practice and a shoot-around before Ernie Grunfeld ordered him to stay home for Game 4 of the series. The next day the unrepentant (contrary to reports he did not insult or challenge Grunfeld or Eddie Jordan in Monday's meeting) 23-year-old was suspended for the remainder of the playoffs. The very next day several teams called the Wizards inquiring about trading for him.

Living in the Washington DC area it was covered pretty extensively. He called in sick with a "stomach virus" after complaining about a lack of playing time in the previous playoff game.

Hey what about this part of the article - pretty telling about Kwame:

In the final analysis, Bulls couldn't withstand the loss of both Eddy Curry (if nothing else his big body would've punished the Wizards) and Kwame Brown. "He consistently disrupted their offense," remarked a member of The Chicago 12. "His teammates were constantly telling him he should be over or over there."
