I believe Saban himself has said we'll use a 3-4 alignment approximately 20 percent of the time. I think people need to lighten up on the 3-4/4-3 issue, including the people who keep coming up and bashing anyone who talks about personnel from a 3-4 perspective.
The fact of the matter is, while Saban will not actually run a base 3-4 (for now, we don't know if he will ever change this), his defense will run on many of the same principles and his personnel strategy will share many values with a traditional 3-4 defense's personnel strategy. When someone on the board talks about a guy being a good 3-4 OLB, or talks about Jason Taylor being a good 3-4 OLB, they shouldn't necessarily be blasted for accusing Saban of running a 3-4 say, 80% of the time instead of just 20%. The bottom line is if you talk about a guy who is a good candidate to be a 3-4 ILB or OLB, or DE or even NT, chances are, the guy will fit into this "4-3" defense that Saban will be running.
So I think it is time to drop the subject.
