Serge Ibaka is known for his ridiculous wing-span and his blocking ability. On Thursday night against The Miami Heat in Game 2 of The NBA Finals, Ibaka blocked LeBron James and let him know about it. Ibaka followed up the block with the famous Dikembe Mutombo finger wag. You need to do what you can to keep your home team fans in the game, but when down by more than ten points you may want to rethink the wag. The block happens 20 seconds into the video.
