It isn't that you are always victim to these, it is that it requires this sort of performance to derail Alabama right now. Other teams falter/fall to lesser teams because they are not focused or simply not as good/deep as advertised. Alabama seems to be prepared every week, has great depth and is motivated - so it takes this sort of performance. Frankly, you remember them because they are the only "blips" in the last 2 seasons, in which you are completely destroying every team that doesn't get this sort of performance from their QB. The lone exception - the regular season game against LSU last year - a game lost as a result of 5 missed FGs.
What does that tell us? That Alabama can lose, but it will take one of those type of games for it to happen.
