I really think the biggest issues are personnel based than mentally based. You can make a lot in college by being intense and focused but you avoid these sort of games truly by being sound across the board. Saban has said before you can't get a team's best performance more than a few times a year, so he tries to make up for that by getting his teams executing almost off muscle memory. So even if they aren't at the intensity level he'd like, they are still confident in what they are seeing and what they need to do to stop it.
This is where the youth is showing up on offense and defense. Yeldon has lost the ball twice - though one was a bad handoff perhaps - in consecutive weeks; first time starters are getting lost a bit in their assignments. Intensity growing from the end of the first onward helped get Alabama back into the game but they weren't executing with consistency to seal the deal. Granted intensity and focus might have staved off that first quarter onslaught but truly it was exploitation of weaknesses that got us in that hole.
The thing is, though I might be a little frank with our deficiencies, all teams have areas they're trying to mask...even the undefeated teams. There have been very few undefeated teams that were truly untouchable by anyone in football. Usually they missed out on some team that matched up well, they got a few bounces, or other parts of their squad overwhelmed any other deficiency. Unless you're 2001 Miami or 1995 Nebraska, every national champion had some things that could have damned them but it simply never materialized or they got a little fortunate. Alabama has the tools to overcome their deficiencies and win the state, division, and conference. I think it starts with us reasserting "Alabama football" on the offensive side of the ball. We need to limit opponent's possession through the run game. We need to get back to mentality that sometimes we have to run when they look like they're playing the run to make a statement instead of simply checking into a pass play. The defense needs the front seven to assert themselves on the game and help their teammates in the secondary. They've put those guys into tough situations the last few weeks by poor tackling and ineffective pressure.
We're not going to get better by hoping a deficiency this late in the season repairs itself. We're going to win by doing what we are suppose to be great at doing and maybe even a little better.
