I will speak of my experience with a four man front vs the 3 which was previously the base. I realize they were in and out of a 4 man front but I believe the defensive philosophy was similar with either front in that it was designed for maximum containment. It limited the run game and forced the quarterback to throw accurately. It generally worked like a charm until we faced a mobile QB who could throw accurately and then it didn't. The 4 man front is designed more for attacking the offense, penetration is at a premium. When it works it's a soul crushing nightmare for the other team. When it breaks down it can lead to quick scores depending on how good the secondary is. Given the choice between the two, I'd probably want the more aggressive D. To me just beating Auburn isn't good enough. I want to make them cry.
