There has been some debate - and in some cases, insistence - that new Dolphins head coach Nick Saban will run a 3-4 defense. In making such assertions, press and fans alike take those numbers literally, anticipating only three down linemen to face off against the interior offensive line. However, it appears that the media, in particular, have confused any defense while places a defensive tackle over or on either shoulder of the center as being a "3-4". What such a technique (normally called the 'zero technique' by coaches) defines is an 'odd' defense, and defenses have played four down linemen in odd defenses for years. This is normally accomplished by sliding those linemen to or away from the strong side of the offense.
