I agree that Alabama should take Auburn seriously. I disagree that Alabama tends to not take Auburn as seriously as AU does them, though that is impossible to measure. In fact, IMO, Saban tends to get a bit “tight” in the AU game because he wants it so bad. Of course, the team reflects that. IMO, that is the primary reason that Alabama sometimes struggles vs AU when they shouldn't, not only in JH but in BDS too. Hopefully, Bryce's heroics in '21 broke AU's spirit a little. That was about as gut-wrenching a loss as a mediocre team could suffer.
IMO, AU's overall success in JH is a myth but that "Alabama doesn't care as much as AU" is also a myth. They care for different reasons but Alabama and its players care VERY much, almost too much. In 2016 in BDS, the TO averse, incredibly jittery, "cool" Jalen Hurts threw 2 of his 9 ints and fumbled twice, both recovered by Alabama and almost fumbled a couple of other times - just had trouble catching good snaps in the shotgun he was so nervous. Bama outgained them 500-180 but won just 30-12, 13-10 at the half. In 2017 Jalen and the entire team became more than discombobulated in JH, it was embarrassing to see them implode, something Alabama almost never does. All because of nerves at the thought of losing to AU. Jalen probably reflected CNS more than any other player he's had. The light-hearted Tua never had problems with AU, he put up 50+ on them in his only game vs them. It would have been interesting to see him play in JH, which he never did. Saban couldn't affect him.
