I've been harping on that for a while. It's not natural or normal for a team to play at a high level constantly. I mean sure, you can reel off ten win seasons if you're really on a roll, but if you want to win championships, there almost inevitably has to be an ebb and flow. You end up with a point in which you are throwing inexperienced kids out there to the wolves, than a season or two later, they're prepared to play for a championship. It's how a team like Auburn can make such a rapid turnaround.
Someone complained that Ole Miss had basically the same guys as last year (like 9 returning starters on defense) and basically said Alabama should have beaten them as badly. Well, the issue they were overlooking is that Alabama doesn't have the same guys as last year. So yeah, I think we're in general agreement. The Alabama team is experienced, and especially in defense, virtually anyone who is a starter is going to leave early (even Vinny, who probably could have settled that secondary down a bit), creating perpetual inexperience.
The bright side of that was that if Alabama could survive further into the season, they had a chance to improve as the season went on. However, something like 11 ranked teams lost. Another week like that and Alabama will have their chance to get better than the team that played Ole Miss and be back in contention.
