The Dallas Mavericks completed a close win over the Oklahoma City Thunder on Sunday night, but the game shouldn't have been as close as it was due to a massive mistake by the NBA.

Dallas led by around 10 points for most of the fourth quarter, but the game got a little squirrelly at the end, with the Thunder scoring 10 points in the final 1:16 of the game, even having a chance to win at the end after the Mavs didn't come down with an intentionally missed free throw.
