The Play

[Jurassic Referee]

I guess my real question is does "outside field of vision" only refer to a screen that is set behind someone? For this play to work B1 is sort of hopping (not moving real fast) down the endline so that A1 does not have to turn and run down the endline because then he would see screener B2. A1 is moving sideways and does not see B2. B2's screen is legally set. When A1 makes contact, he stops or tries to stop. Inadverdent contact?

Ron, the screening concepts are outlined in Rule 10-6-3. As per rule 10-6-3b, if the defender is stationary when the scrren is set, the screener can set up from the side or front as close as the screener can get, short of contact. If the defender is moving when the screen is set, you use the concept outlined in R10-6-3c. You have to allow time and distance for the defender to avoid contact with the screener, usually 1-2 steps, but never more than 2 steps.
Unless the defender pushes through the screen, it's usually ruled incidental contact.
