Team: Washington Wizards
Players involved: Javaris Crittenton, Gilbert Arenas
Out of any fight between teammates, this incident is the most infamous. Details as to what truly went down are still sketchy, but it is known that an argument took place between Gilbert Arenas and Javaris Crittenton on the team plane on Dec. 20, 2009, reportedly stemming from a game of cards between JaVale McGee and Crittenton. Apparently, McGee wasn't paying up, and Arenas had tried to step in as a peacemaker, but to what end remains unclear. Various witnesses said that Arenas threatened to shoot Crittenton, who retaliated by doing the same thing.
On Dec. 21, Arenas tried to back up his talk by laying out of all his guns in front of Crittenton's locker. Crittenton responded by pulling out his own firearm. From there, things got ugly, as the media got involved and action had to be taken by the league and legal authorities. Arenas was eventually charged with a felony for carrying an unlicensed pistol outside a home or business. He received two years probation and 30 days in a halfway house for the crime. Crittenton was only given a misdemeanor gun possession charge and a year of probation, but both athletes were suspended for the remainder of the season by Stern.
