[Coach Rip]

"Completion: TTQB - A pass is complete if the ball hits any portion of the BuzzBall Spot Passing Target in the air, including the base, before hitting the field, and if it did not hit any other player before doing so. Completed passes on or beyond the LOS may not be advanced and the play is over.
Once a pass is completed no offensive players can be pivoted unless the receiver who caught the ball remains behind the LOS after the catch. In such a case only the receiver who caught the ball can be pivoted on offense.
After this type of completion the defense is allowed to pivot any unengaged defensive players to attempt a tackle. Once a pass is completed and all pivots are made the switch is given to the referee or defensive coach to control, the board is turned on and the play is resolved. Completing a pass to an unengaged offensive lineman is a penalty - 10 yds from the LOS, if accepted.
