You're looking at a screenshot from Agile Sports' interactive playbook titled the "Huddle." It is a computer program designed by three Nebraska graduate students and it allows players and coaches to be in strategic communication through the Internet.
Here are a few examples of the system's use: A Nebraska coach on a recruiting trip in Dallas can write notes or draw diagrams on game video with a telestrator pen and those notes can be viewed by a player in his dorm room in Lincoln.
That same coach can record comments about plays that can be heard by players when they log in. A coach can also text message players to log into the system to study highlighted plays.
Nebraska started using the program last year and a handful of other teams are reviewing it for possible use. The New York Jets have already adopted it and about half the teams in the NFL are also considering it.
