Many years ago (I believe during the Carter Administration) , when stretching the chain from 45 to 45 in pregame, we discovered the chains were a yard short

. I ,then being a wide-eyed linesman

, quickly summonsed my whitehat. My whitehat quickly summonsed the athletic director

. The following occurred :
(1) The

AD explained that when the goal posts were cemented in, they were 121 yards
apart

.
(2) The AD felt the expense of "replanting" the goal posts could be spared by having 11
yards from 45 to 45.

(3) The white hat suggested that, when painting the lines next Fall, he should make each
endzone 10 1/2 yards.
(4) We rechecked the chains from 45 to 35 - they were correct.
......and the band played on......
On kickoffs, R's retaining line was 10 1/2 yards for the remainder of the season. No one seemed to mind. New spiffy one pole goal posts were put in correctly a couple of years later. The visiting teams were advised of the longer field/longer endzones and no one seemed to mind. One yard hash marks were only seen on TV back then and some fields only had lines every 10 yards and no one seemed to mind.
....So that's my line about lines...I 'spect new rules will be posted this week....I 'spect we'll have more exciting stuff to yap about then...Ayuh...
