This has bugged me for a while -- not every WR screen is a bubble. KU throws very few "bubble" screens. A bubble is usually to the inside receiver arching (bubbling) towards the sideline. He is running away from his defender and the O is trying to create 2 on 1s on the outside. What we throw, more often than not, is the "now" screen. Throw it wide and hope to beat your man 1on 1 or get a block to get somewhere. Those haven't worked too well. I would actually like to see more bubble or some tunnel or jail breaks in our screen game. Here is a good article for you to reference: http://playfastfootball.blogspot.com/2014/04/coaching-effective-screen-game.html
