A potentially interesting play situation from the other forum.
3/4 at A-40. Team A is in tight formation - 2 tight ends and 2 flanker backs just outside the 2 tight ends with a single running back in the backfield. The same alignment that they have used for 1st and 2nd down.
QB A11 looks over the alignment, goes under center A51 and calls ready, then set. On the "set", all 7 A linemen go from standing up to "down" position, but instead of hand(s) on the ground, rest forearms on their knees. On next sound, the 6 linemen, except for the snapper A51, who never moves, quickly step back and stand up. Ball is not snapped but team B linemen B61, B62, B63 and B64 cross the LOS and contact team A linemen.
What do we have, and what are the keys here in deciding either false start on A or offside on B?
