That’s not the issue, only defensive penalties allow a replay of the down. You do not get a replay of the down if it’s an offensive penalty. The clock hit 0 before the TD, and with pass interference on the offense, the steelers were allowed to accept and with no time left on the clock the game is over. You can end on an accepted offensive penalty, you can’t on a defensive, there must be an untimed down if the defensive penalty is accepted.
