On August 16 in New York City, Nike Basketball is hosting the ultimate pick-up game of the summer, a showdown at the Tournament of Champions with two teams coached by NBA stars Kevin Durant and James Harden. Want in? Just do any of the following: Tweet, Instagram, Vine, YouTube or even record a SoundCloud with the hashtag #SUMMERISSERIOUS and the folks at Nike will enter you into the draft. (Depending on the social media service you use, you can describe your game, take a photo of yourself playing, shoot some video of your sick moves or record audio of your trash-talk.) KD and Harden will be selecting players off the ‘Net for their respectives teams on August 13. Yep, summer just got serious.
