I started to say what I have to say here on the "2009 poll" thread.
It has been my expereince that if Alabama has a defense, Alabama wins -- regardless of what the offense does or who the coach is. If the Alabama defense shuts down the other team, the other team nineteen times out of twenty doesn't win. Maybe twenty out of twenty.
We lost to Florida last year because the defense didn't stop Tebow in the fourth quarter. We lost to Utah because our defense didn't stop their offense.
I just read an LSU thread on Tigerrant.com, and it certainly seems to me that LSU fans are in a typical state of denial concerning Alabama football, when Alabama has a defense like most everyone is predicting. A lot of LSU people are saying that Ole Miss is the team to beat in the West this year. Well, if they are, they better have a better defense than Alabama does.
If you have great athletes, great coaching, and great depth on defense, you can bank on consistency. That seems to be what we have this year. The "holes" we have, everyone pretty well agrees, will not be on defense. Therefore, our offense cannot be banked upon as much as the defense. But as someone has said here, what of it? -- If the other team struggles to get into double figures, we will beat them every time.
The famous saying of Vince Lombardi when he met Bear Bryant: "People wonder how you win -- you do it by keeping the other team from scoring."
If this present Bama defense learns to stop a good spread offense, I foresee difficulty for anyone beating Alabama this year. It could happen, but it won't be easy.
