Science of NFL Football

In America, the autumn season means two things--back to school and back to football. To celebrate both events, NBC News' educational arm, NBC Learn, is teaming up with the National Science Foundation (NSF) and the National Football League (NFL) to release the "Science of NFL Football"--an informative, 10-part video series that explores the science behind America's most beloved sport.
