No, but they'll just keep stalling rather than scrap so many historic rivalries, it doesn't make sense to sacrifice these games that put eyeballs on the screen just so Tennessee can play Texas &M twice in 4 years instead of 1 or 2 times in 4-5 years. I called the stall tactic before it was announced for 2024 too.
If they don't reach an agreement and there is no further expansion, we'll see a schedule something like this for 2026-27
Alabama
Kentucky
Vanderbilt
And then 5 of the remaining 7:
Texas
Texas A&M
South Carolina
Ole Miss
Auburn
Missouri
LSU
And then they'll flip flop them home and away. That will mean we played 13 out of the 15 other teams twice in 4 years, and we'll get the 2 we missed on the next go round. That's a lot less pain to the SEC's product and its fans that scraping the TSIO or Auburn-Georgia or LSU-Ole Miss, etc. It's also basically how the SEC schedule was pre-divisions, you played your rivals and fit everyone else in as best you could.
