Oh, there's no way the ratings for this will match 2018. Won't happen.
In regard to the "SEC" national champions over the years, let's just look at this.
BAMA- 2009, 2011, 2012, 2015, 2017, 2020
LSU- 2003* (USC got left out of the BCS title game despite being ranked No. 1 in both polls- split title), 2007 (two losses"), 2019
Florida- 2006, 2008
Auburn- 2010
Tennessee- 1998
So 5 different teams have won a national championship since the BCS/CFP era that started in 1998 and Tennessee hasn't been relevant since 1998. So when they chant "SEC", it's all about these teams above in a conference of 14 teams.
