Under Kalen DeBoer, all 3 of Alabama's SEC games have been decided by 7 points or fewer: 41-34 home win over Georgia on 9/28, 40-35 road loss at Vanderbilt on 10/5, and 27-25 home win over South Carolina on 10/12. I think Alabama will lose two more road games at Tennessee on Saturday and LSU on 11/9. Even Nick Saban lost road games at Tennessee and LSU 2 years ago. If that happens, they will lose 3 games for the first time since a 10-3 (5-3 SEC) finish in 2010 and consecutive regular season games for the first time since 2007.
In 2020, Alabama finished as an undefeated 13-0 CFP national champion. 12 of those 13 wins were by 15+ points each, and the only exception was their 52-46 win over Florida in the SEC Championship Game. However, Alabama had played in close games much more frequently in Nick Saban's last 3 seasons.
2021: 5 of their 8 SEC games were decided by 7 points or fewer: 4 wins over Florida (away), LSU (home), Arkansas (home), and Auburn (away) and one loss to Texas A&M (away)
2022: 5 of 9 games against Power 4 teams decided by 6 points or fewer; 3 wins over Texas (away), Texas A&M (home), and Ole Miss (away) and 2 losses to Tennessee (away) and LSU (away)
2023: 3 regular season wins by 6 points or fewer over Texas A&M (away), Arkansas (home), and Auburn (away). Then a close win over Georgia in the SEC Championship and a close loss to eventual nation champion Michigan in the CFP semifinal.
The frequency of close games in Nick Saban's last 3 seasons indicates that Alabama already started losing some dominance in 2021. The NIL and transfer portal have increased parity because it has made it much harder to stack talent. Kalen DeBoer is learning how tough SEC football games are, even against the worst SEC teams.
