The Colts moved from the 4-3 defense to a 3-4 hybrid last season under Chuck Pagano, a big difference for Indianapolis fans who had gotten used to the 4-man down line that the Colts' Tampa-2 defense used during the Dungy years.
While some fans took the change in stride, the transition has caused confusion among others, especially considering the fact that the Colts used a 4-man front more often than not in 2012 anyway, even if they called it a 3-4 base defense. The confusion has caused some communication issues amongst fans, and now is as good of a time as any to clarify how the defensive line is generally used, especially with players like Ricky Jean-Francois, Aubrayo Franklin, Josh Chapman and Montori Hughes coming into the fold for 2013.
The Colts' defense in 2012 ran a 3-4, which traditionally has three down linemen: a nose tackle and two defensive ends. In the old 4-3, there were two defensive ends and two defensive tackles (a one-tech nose tackle and a three-tech “under” tackle). The 4-3 was generally a one-gap system, which means the down linemen try to shoot their gaps and get to the backfield, while the linebackers react quickly. The linebackers included a WILL, MIKE, and SAM (weak, middle, and strong-side).no comments
