Jim’s play…
K 4/10 @ K-10. R15 is standing at the K-45 waiting to catch the punt. As R15 attempts to catch the punt, K85 stands in his way. R15 crashes into K85. The ball rolls, untouched, out of bounds @ 50 . R elects to take the ball with an awarded fair catch @ K-45.
On the next play from scrimmage, A15 attempts to catch a forward pass, B85 stands in his way. A15 crashes into B85 whose standing @ K-20. Give all options!

Clear that K85’s contact is KCI. Assuming that B85’s obstruction of A15’s movement toward the ball is DPI (a pretty good assumption based on the description), A has the following options:

FEDERATION: A’s ball 1-10 @ B’s 30. Assuming the pass fell incomplete, clock starts on the snap, or A could decline the penalty and play 2-10 @ B’s 45, or they could decline the distance portion of the penalty and play 1-10 from B’s 45 (last two options are ridiculous…let’s ignore them). And since the down being replayed is a down following an awarded fair catch, A could also choose to free kick from B’s 30 with a chance of scoring a FG – 3 pts.

NCAA: A’s ball 1-10 from B’s 30 since the foul was more than 15 yards in advance of the previous spot. No option to free kick in an awarded fair catch situation for NCAA rules. Here too, clock on the snap.

Did I forget anything Jim???
