The fourth day of class in Bob Davie's Football 101 season-long course breaks down the screen pass.

Bubble screen and jail break screen are described here. The bubble goes to a receiver (almost always slot) cutting toward the sideline and away from the QB, with the key being the outside WR's block. EDIT TO ADD- This is literally why it's called a bubble screen- because the receiver bubbles away from the QB. Jail break usually goes to an outside receiver cutting toward with the QB, with the OL getting out to block. Price and Rosenbach loved the bubble screen. I frankly don't remember if Sturdy ran it much or not. Leach did not. Nor did Morris. Arbuckle has a little.
As stated, sponge doesn't know what a bubble screen is, otherwise he would have been able to speak intelligently on the issue during the last 20+ years. He probably thinks buffalo, elk, antelope and deer are all the same.
I can't see the imbedded videos in Loyal's post.
