Clock not running on PAT question...

[Official_21]

What is the rationale behind the game clock not running after a PAT?

Always wondered this ever since I became a clock operator.

If not a media timeout, the time period is at least a minute plus the play clock after the RFP for the kickoff.

You might go back and re-read the question.

I don't remember exactly but I think because it is considered an extension of the scoring down.  I may be totally wrong.

Now I am confused what is being asked, question in post says "after", title of thread is "on".

I believe the question is "Why does the game clock NOT run during a try down?" As frickin' old as I am, I can't answer that question. Been that way forever. Knute Rockne might not even know the answer to that question. But, as the rule itself states, a try is a 'special' interval in the game. So, it is not surprising that the game clock does not run.
I have a feeling that is was the first effort at "tie-breaking" the games. Look where we are now.

According to Anatomy of a Game by David Nelson, the rule dates to 1894 and 1898 rules changes.
