Going back to Nick Saban's renewal of Alabama Football in the 2009 season, the SEC has had 16 undefeated conference seasons. During that 16-season period, only seven programs made the SEC Championship Game, plus new arrival Texas in 2024. The 16 SEC Championships were gained by only four teams. The Alabama Crimson Tide won nine of them. Georgia won three, followed by LSU and Auburn with two each. The point being there was nothing close to parity in the SEC.
Going into the 2025 season, the situation has changed. The bottom tier of the league, Mississippi State, Kentucky, Arkansas, and probably Vanderbilt, are unlikely to pull off many upsets in what, combined, will be few conference wins.
