"Because when a quarterback drops back in the pocket to throw the ball, he automatically turns to his right because he's going to throw from that side, so it leaves his left side blind. That's called the blind side. If you ever seen the movie about Michael Orr with I forgot the young lady's name that played in the movie, she's made a lot of different movies. It'll come to me eventually. But look it up. It's called the blind side."
