4th qt, 1 point game. 7
Seconds remain in the game. A 2 & 8 @50. A1 passes to a2. B 3 is flagged for defensive holding. .4 seconds remain on the clock. I know enforcement of pentaly, but what happens with clock after administration of pentaly? Clock starts on ready? Untimed down? Clock didn't run out DURING play. Start on snap?
