I just hope we don't have stupid Free Kick mechanics for this.
If they were smart they would just keep it simple. Line up like a normal free kick, but put the CJ and R under the uprights. Everyone else in their normal position.
7 man, use the R and F. I chose F since if you were to take someone off of a restraining line for this play, it would be someone on R's since they're not going to onside kick. You can easily do B as well.
For a crew of 7, yeah, send the F or S back. Don’t need 2 on the receiving team’s restraining line. Although probably won’t be illegal, an onside kick would be the dumbest move imaginable. Why? You’ve got the ball. Just take the scrimmage series and play ball, unless you need 3 points to tie or win, and there is only time for one down.
So, if they score, and there is time remaining, what happens after the kick? A free kick, just like after any other field goal?
Which begs another question? If the field goal is successful, then the ball would not have been legally touched in the field of play, so the clock wouldn't run. Correct?
