Video: Kings' Derrick Williams blows uncontested off-the-backboard dunk

Kings forward Derrick Williams was unable to complete an uncontested off-the-backboard alley-oop to himself during garbage time of Sacramento's 99-70 home victory over Chicago on Monday.

This was a coach's nightmare in every sense of the phrase: unnecessarily flashy, terribly executed and bound to encourage thousands of people to simultaneously write "Shaqtin' a fool!" on their Twitter accounts.

With a little more than three minutes remaining and Sacramento up 95-67, Williams stepped in front of a D.J. Augustin pass and took off for the races. As he approached the foul line, Williams scooped an under-handed pass to himself off the glass, gathering himself for a possible two-handed throwdown. Unfortunately, Williams couldn't quite get his grip on the return pass, and he wound up inadvertently batting the ball off the glass again as the Sleep Train Arena crowd groaned. Bulls forward Erik Murphy was able to control the ball off the second bounce, and Chicago went the other way with possession.

From hot to not in the blink of an eye. At least the 2011 No. 2 pick had the good sense to laugh at his own goof.

"You know it's bad when your mom [texts] you, 'What was that!?'," Williams wrote on Twitter.

Kings play-by-play announcer Grant Napear joined Williams' mother in cracking wise about the blown dunk.

"Look out below," Napear began, before the play totally unfolded. He was then forced to add: "We'll see you on the not so [top] plays of the week."

Williams has been here before, as he missed a series of dunk attempts during the 2012 Slam Dunk Contest before finishing in last place out of four competitors.

Sacramento went on to claim an easy victory despite Williams' flub, holding Chicago to just 13 fourth-quarter points and 28.2 percent shooting for the game. Williams finished with five points (on 1-for-4 shooting) and nine rebounds. DeMarcus Cousins tallied a game-high 25 points (on 8-for-15 shooting), 16 rebounds and four assists to pace the Kings.

Jimmy Butler led Chicago with a team-high 17 points (on 4-for-11 shooting), five rebounds and three steals.
