NBA Playoffs 2013: Thunder’s Backcourt Pulls Off First Ever ‘Double Charge’ In NBA History [VIDEO]

After taking a 3-0 lead in the series, the Oklahoma City Thunder suddenly finds themselves in dangerous territory after failing to finish off the Houston Rockets in the last two games.

Now, with the series returning to Houston for Game 6, the Thunder are expected to pull out any kind of tricks - the flopping and the Hacka-Asik - just to get the upper hand in Friday's crucial ballgame.

The 2013 NBA playoffs have already seen the weirdest plays and a number of mind-boggling tactics that one would never imagine.

But what happened at the 6:31 minute mark of the second quarter of Game 5 might have been a first in the history of the NBA.

With Omer Asik rolling hard to the basket, Derek Fisher and Thabo Sefolosha synchronously took a step forward just outside the restricted area to draw what basketball analysts called a 'double-charge'

A double charge? Come on! Asik might be a 7-foot, 255-pound behemoth but would have that type of collision produced such great push? Asik sent Fisher and Sefolosha flying back with great sheer force, almost hard to believe.

Notorious for drawing fouls by flopping, Fisher might have been a pretty good mentor to Sefolosha.

Too bad for Asik, the Thunder's assault on the Houston Rockets center didn't stop there as the Turkish bigman became the latest victim of the infamous tactic often used against player with bad free-throw clip.

The funny part is Kevin Durant didn't even know the name of the player they were slapping in hope of disrupting the Rockets rhythm.

"We used hack-a ..." he stuttered, trying to say Asik's name. "Whatever his name is, that kind of slowed the rhythm down a bit," Kevin Durant said during the post-game press conference, according to Yahoo.com.

Game 6 will surely be another tactical tussle between the two ball clubs. The Rockets will try to level the series at 3-3 and become the first team to comeback from a 0-3 deficit while the Thunder look to progress to the Western Conference finals for third consecutive year.
