22 1/2" step...oh how I remember those days...
I do believe you are correct though that we changed the end zones when we went from turf to grass...I believe it was in '94...not sure the reason.
I do remember one of my friends at the time, who ia a big Bama fan said that we actually did it to make our endzone slightly smaller...LOL...said someone on the staff did a study and found out that like 90 percent of touchdowns against us were in the air, along the back or side edges. Therefore we made the endzones slightly smaller to decrease that number. Obviously teh smaller end zone would be highlighted by teh squares not all fitting correctly into the zone...I know right...leave it a BAMA fan...:crazy:
