LeBron James and Draymond Green have been trolling each other on social media and they are officially the kings of pettiness. Last year, when LeBron returned to the Cleveland Cavaliers, he rocked an "Ultimate Warrior" shirt as a way of throwing shade to the Golden State Warriors for beating them in the NBA Finals. Unsurprisingly, after the Warriors defeated the Cavs in this year's NBA Finals, Draymond Green got his revenge on LeBron.
