Agreed. False start on A, no foul by B.
I'm pretty sure that's right, but I posted it because I couldn't find it in the ARs and I can't recall it coming up in a bulletin or quiz that I know of. Live ball fouls never offset dead ball fouls, and the snap caused a false start so there's no live ball. It's just weird that, if this were the other kind of illegal shift, then Team B becomes guilty of wrongdoing, having committed the same conduct as before.
On the kickoff play, both of these are fouls for a fee kick out of bounds. In a, the clock starts on the touching by Team A because it is a legal touch and stops when the ball touches out of bounds. This would trigger a 10 second runoff since it was a foul before a change of team possession that caused the clock to stop and there was less than 1 minute left in the half. The game is over, Team B wins. In situation b, there is no runoff because the clock never started since the Team A player was not in bounds when he touched the kick. The ball is dead immediately upon being picked by Team A. Team B's ball at the A-41, 1st and 10 still with 9 seconds on the clock.
This one I posted because I don't recall if RR has ever said that KOB causes a runoff or not. It could potentially matter if Team A has all three timeouts and the game clock is just right, like 0:20.
Without guidance either way, I know what I'd say if it happened to me tomorrow: get real, Team A gained no advantage by conserving time here, a runoff is clearly not what the spirit of the rule intends.
