Clock management at the end

its a remarkably silly rule IMO, but:

Section 3.

AR 4.3 (F)

(f) If the game clock is stopped after a down in which there was a foul by either team, following enforcement or declination of a penalty, the game clock will start as if the foul had not occurred,except that the clock will start on the snap if:
(1) the foul occurs after the two-minute warning of the first half;
(2) the foul occurs inside the last five minutes of the second half; or
(3) a specific rule prescribes otherwise.

Giants fans were hammering this hard last year after their first meeting with the Cowboys, because the Cowboys basically got a free timeout for jumping offsides.
