DeMarcus Cousins is a bad, bad man.
With his Sacramento Kings leading the Boston Celtics midway through the third quarter Friday night, Cousins took control of the ball on a fast break and absolutely steamrolled Celtics forward Jae Crowder with a poster slam.
That has to hurt, in more ways than one.
Crowder quickly recovered, though, and gave Cousins a taste of his own medicine on the very next trip down the floor.
Everyone loves a good dunk-off.
