This is probably a good thing for college football as a whole, as far as keeping things interesting for more people and not just having more of the SEC invitational. Here's the last 24 years broken up into 3 separate eight-year periods.
1999-2006 BCS: SEC places 2 of the 16 teams to make the title game, wins 2 of the 8 titles (1999 Tennessee, 2004 LSU)
2007-2014 BCS: SEC places 9 of the 16 teams to make the title game, wins 7 of the 8 titles (2007 Florida, 2008 LSU, 2009 Florida, 2010 Alabama, 2011 Auburn, 2012 Alabama, 2013 Alabama, 2014 Auburn)
2015-2022 CFP: SEC places 10 of the 32 teams to make the playoffs, wins 5 of the 8 titles (2016 Alabama, 2018 Alabama, 2020 LSU, 2021 Alabama, 2022 Georgia)
I haven't read any of the articles yet but I would guess if it goes to 12 teams, that means at least at least eight more shots a year for a not-SEC team to win it. Still have to win on the field, but everyone has good and bad days. I bet over time we win more like 1/3 of them this way, instead of more than half.
