re: Why do SEC football schedules remain constant year over year?

because of the sacred games
Cocktail party is not moving
Bama Tenn has to be around that time
Fla Tenn has always been early game along with USC UGA

Of course all the end of year games which are not SEC play a part like Clemson USC and Fla Fla St

LSU has played Auburn at different times but every other game is pretty consistent, I do like A&M game last every year much better than hogs
