Rajon Rondo and Deron Williams

Rajon Rondo cannot stay out of his own way, or out of his opponent's way. On Tuesday night, while sitting out with a back injury, Rondo tried to kick the Mavericks' Deron Williams from the sidelines.

Rondo. Bro. Not cool.

Karma bit Rondo in the butt later. Williams hit a buzzer-beating 3-pointer to win the game for the Mavericks in triple-overtime, 117-116.

A few weeks earlier, Rondo's image took a hit when he called NBA referee Bill Kennedy a gay slur. Kennedy subsequently announced that he is, in fact, gay.

Rondo, who had a tumultuous half-season with the Mavericks in 2014-15, moved on to the Kings this offseason. Williams replaced him as Dallas' starting point guard.
