re: It was obvious live the ball was spiked with 1

I thought the 10 second runoff rule only applies if the clock would have normally been running after the play in question. They never runoff the 10 seconds after an incomplete pass, timeout, out of bounds, etc. It's done that way so that if the offense can't otherwise stop the clock and the clock is running, they don't just commit a penalty to stop the running clock.

So since they spiked the ball, stopping the clock with 1 second left, the refs assess the penalty but don't run off the 10 seconds because the clock wouldn't be running.

It seems pretty fricked up in this situation but that was my understanding.
