Following the Wizards’ lackluster season-opening loss at Miami on Wednesday, Coach Randy Wittman pointed to a lack of defensive toughness as the culprit.

“Tonight had nothing to do with our offense,” Wittman told reporters. “We just got beat off the dribble too much. We didn’t have a presence at the rim. We didn’t have a willingness to step in and take a charge and knock somebody down.”

Wizards veteran Rasual Butler showed a willingness to take a charge early in the fourth quarter, but Heat forward James Ennis had other ideas. The rookie, who spent last season in the Australian Basketball League, posterized Butler with a one-handed slam that, two days into the NBA season, qualifies as the dunk of the year.

Ennis’s dunk is just as vicious from another angle:

Butler, who survived the slam, congratulated Ennis on his play via Twitter on Thursday morning.

Great play on that young mans part @JamesDa_Truth the breaks of the game when you're competing trying to make a winning play for your team — Rasual Butler (@RasualButler45) October 30, 2014

‘Twas a nice dunk.

Thanks to @Truth_About_It for the Vines.
