Trash-talking is a part of basketball. It's been a part of the NBA since the beginning of times, and even though some say the league has softened over the past couple of decades, it'll always be there.
It's not unusual to see players taking shots at each other, both on the court and on social media. Add two guys who know each other pretty well to the mix, and you could be in for some fine trash-talking.
That's exactly what happened between a couple of former teammates in Nikola Vucevic and Evan Fournier, who traded some jabs on Twitter a couple of hours ago.
