He was 0-14 on the road against LSU, Georgia and Alabama. His bowl record was horrendous and the worst in our history. The o-line recruiting had been below average not just in the SEC but for P5 teams for over 4 years.
He is a very good man but you can’t do the above and keep your job at Auburn. If Tennessee had hired him they would be firing him in 3 years. The only things that saved Gus were Kevin Steele and the assistants that were former players at Auburn and they could recruit. Everything Gus was personally in charge of producing was average at best.
You are cherry picking his weakness. Let's see what he has achieved.
2013: 12-2 National Title Game Appearance
2014: 8-5 Finished ranked #22 (wins @ #20 Kansas, #15 LSU, #7 Ole Miss)
2015: 7-6 Unranked (Bad Year) Only highlights were wins @ #22 Texas A&M and win over Louisville in opener
2016: 8-5 Finished ranked #24. Schedule was brutal. Most losses were against top 10 teams. Auburn had Alabama, Georgia, Clemson, and Oklahoma on schedule (OU was bowl game).
2017: 10-4 Finished ranked # 10. Beat both Alabama and Georgia (1 of 2 times). Barely lost to Clemson and Georgia second time. Only embarrassment was the UCF loss in bowl game.
2018: 8-5 Finished unranked. Highlight was opening win over #5 Washington.
2019: 9-4 Finished ranked #14. Beat #11 Oregon, #5 Alabama, and # 17 Texas A&M. Were top ten team until he choked against Minnesota.
2020: 6-5 (6-4 against SEC Schedule)
Gus seems to choke a lot in Bowl Games such as Northwestern last year, Minnesota in 2019, and UCF in 2017. I will give you that. However, he had more seasons where Auburn finished in the polls versus not finishing in the polls. He beat Nick Saban 3x, more than anyone out there I think. He never had a losing season. He owned the series against Arkansas, Ole Miss, Miss State, and Texas A&M. Interestingly, his record against Georgia and LSU was about on par with the record against Alabama so I give you that.
However, as a Tennessee fan, I would take this performance in a heartbeat. Especially versus the trash coaching we have had. He wasn't losing regularly to Kentucky, Vandy, Missouri, etc. like some of our dumbass coaches have done. He actually had teams finish in top 20 and actually beat big-name opponents.
I think Auburn fans were expecting too much. I stand by my statement that I would hire Gus in a heartbeat as a Vols fan. He probably could get us back to relevance. Note that we have Alabama and Georgia as annual opponents and we have faired even worse against them then Auburn.
