Interesting story from this first link:
According to multiple sources, Rondo's errors were being pointed out when he arose and began discussing the mistakes of his teammates. Loudly. Using harsh language.
Coach Doc Rivers got up and fired back, and Rondo threw a bottle that shattered the video screen. He bolted from the practice facility and was prevented from returning when he tried later.
The article goes on to detail Rondo's growing maturity and taking ownership of the leadership position he's growing into. Recommended reading.
