I cannot prove its reality, though I assure you it is very real. The ball hits the backboard with such force. Though I would be skeptical if I were you as well.
Background: I am in a NYU Short Film that shot this week at a high school in New Jersey. In between scenes I set up a camera and decided to shoot full court shots with an assistant director, hoping to catch one on video. Then he hit three in a row. Also -- the sweater was part of the wardrobe. And so was my airball.
"I wish I wasn't reloading the front page over and over during the past four days and watching every video. Only taking breaks to comment. Unfortunately I have no choice. Isn't that weird? This is torture. Why am I still watching these videos. Anyhoot, got three more to drudge through today, brother."
