Starting the clock - clarification

[SouthGARef]

The clock was stopped due to a change of possession, but in this case you're technically not awarding B or R a new series because a new series isn't technically awarded until the subsequent ready for play. Since the penalty administration gave the ball backed to A or K, B is thus never awarded the new series. So if the returner was downed inbounds, the clock would start on the whistle. If the returner was downed OOB, the clock would start on the snap.
