Before we even start to talk about this, we should remember: this all happened on 2nd down with about a yard and a half to go!
It was close, but I see the ball was beyond the Neutral Zone when it was picked up by K after rolling between the LOS and the line to gain; so K could not advance it - and the play should have been blown dead when he possessed it. The K player simply advanced a dead ball.
SO, ASSUMMING TIME COULD STILL BE ON THE CLOCK, WHOSE BALL IS IT (OR SHOULD IT BE)? K's ball 4th down and a half yard to go; or R's ball at the dead ball spot?
Rules 5-1-3g and 5-1-4 speak to this issue: 5-1-3g says: The ball belongs to R at the spot of first touching by K if K is first to touch the kicked ball beyond the Expanded Neutral Zone before it is touched beyond this zone by R and before it has come to rest".
Rule 5-1-4 says: "Unless touched by R beyond the Neutral Zone, if the kickers recover the scrimmage kick in or behind the neutral zone, the ball remains live and the down counts". In this play, K appears NOT to have recovered the kick in or behind the NZ and R never touched the ball, so K's possession of the kick should have ended the play.
So, since all this happened on 2nd down, and the officials recognized what happened, is it now 3rd down for K/A at the recovery spot; or is the series concluded? Also, since we don't know how much time, if any, still remained on the clock. The announcers suggested this would be the last play.
Reddings clarifies this by asking: "...Is the scrimmage kick beyond the Neutral Zone when it is touched? If "yes", which is the case here:
>there is no longer a line to gain (the continuity of downs is broken). Therefore,
>>If untouched by R after the kick crossed the expanded neutral zone (which was not the case) and the ball is declared dead (which it wasn't - is it R's ball at the dead ball spot or at the spot of first touching by K (which IS where K picked it up and is short of the line to gain)
>>if R is first to touch the kick (which they didin't), team K may catch or recover the kick (but not advance) and retain possession
>The expanded neutral zone extends two yards beyond the defensive LOS in the field of play (where it was when K picked it up) and disintegrates when the kick has crossed the expanded neutral zone; so...
If, as (incorrectly) ruled, the ball was still live after the K player picked it up, all the R players (technically substitutes) being on the field during a live ball would be guilty of Illegal Substitution - as it could be argued that they really never participated in the play. Since Illegal substitution (no participation) is, by rule, a succeeding spot foul (where the K player possessed it), the play would not have resulted in a new series for K; and, since R was ahead as time expired, the game should have been declared over.
It is also not insignificant that the entire Team K bench was out of the team box, but not on the field, nor did they participate, during a live ball. However, Rule 9-8-1k says being out of the Team Box during a live ball is a WARNING for the first offense; therefore no penalty is enforced.
One way or the other, BOTH teams had too many players on the field (Red) or out of the team box (White). I think all that should "offset"!
