理由出來了：

That hit came after he accused James of flopping on that shove to
the floor and questioned the officiating after the Heat took Game 3,
saying the Bulls weren't going to get the benefit of the calls.
Thibodeau had already addressed the media by the time the punishment
was announced and declined comment through a team spokesman.
解釋了為什麼會罰款：
1.因為公牛教練抱怨LBJ被推倒之後有假摔
（seriously? are you listening to yourself?被推倒的假摔...XD）
2.質疑裁判執法!抱怨判決對公牛不利。
整篇外電太長了啦！明天有考試沒時間翻，如果明天考完還沒有人翻我再來試試。
Wish me luck!
