Perhaps Keyshawn was not guilty of starting the fight only being a party of the altercation but the fact remains he was part of it.
A quote from the Star-Telegram out of Fort Worth, "Bryant has become frustrated with his role as the team's third receiver. His feelings boiled over in practice, with Bryant initially getting into separate arguments with Keyshawn Johnson" posted in the paper on the 9th of June.
Who is to blame? Who is responsible for the explosion when you put gasoline and fire together? The explosion is Keyshawn Johnson's mouth and the Bucs will verify that for you. It certainly will not be his Keyshawn's production on the field (my bet) this year, which is why the Cowboys will try and retain Bryant even after he disrespected the coach.
Give me an athlete and a character such as Andre Johnson any day.
