Here's my thoughts on the 7 years I've followed A&M football.
2022: App State - No single win turns this season around. The App State loss may be the single worst loss in recent seaons, so erasing that would be the move.
2021: LSU - This loss really soured the end of the season. While we weren't going to win the west at 5-3, I can't help but think that an extra win here turns this season into a more favorable outcome, especially given the QB situation. LSU was significantly worse than us with a lame duck coach; their game winning drive was really hard to watch.
2020: Alabama - This is the only choice here. Do we beat Florida again in the SEC final? Maybe, maybe not. However, we still make the playoff even with a loss.
2019: There's a few good options here. None really change the season much. Auburn was really the only loss that wasn't entirely expected from a statistical standpoint. The Georgia loss was frustrating in the sense that some calls went against us; it would've been nice to come into Athens and make a statement. Finally, a win at LSU would've been nice to have given their dominance that season. Not sure which one to pick, but I'd lean towards LSU or maybe Georgia.
2018: Clemson - An extra SEC win wouldn't have gotten us to Atlanta, so the agonizing loss at home to Clemson is the pick. We had ALL the momentum in the 4th quarter and fell victim to an unfortunate fumble call out the end zone that may or may not have been correct, but there wasn't enough evidence to overturn. Would've been a really special way to start Jimbo's era, although the LSU game filled that box later that season.
2017: Wake Forest - Not biting at the UCLA game because that was probably what got Sumlin fired. Not sure any other extra SEC win saves his job, but not taking the chance. 2017 was needed to get Sumlin out.
2016: Mississippi State - Assuming Trevor Knight doesn't get hurt and beats State, who knows where this season ends up. One additional SEC win doesn't change much, as Alabama went 8-0 that year.
