For as much as everyone loves the game of basketball, one of the most frustrating things that can happen in an NBA game is the final couple of minutes taking 20 or 30 minutes to finish up. Constant timeouts are one of the issues, but arguably the biggest cause of this is the official reviews, which seem to drag on forever even on the most obvious of calls.
In the final two minutes of the game, officials can automatically review any call they are unsure about and the most common of those is the out-of-bounds play. Any close call will see the officials go over to the monitor and check in super slow motion whose fingertips the ball went out on.
