So having said that, there needs to be a distinction in the game between a 3-4 where the DE lines up outside the tackle (1 Gap 3-4 Wade Phillips style) vs a 3-4 where the DE lines up head up (Eagles, Steelers, and 49ers immediately come to mind).

Just fyi, the 49ers are a 1 Gap under front almost all the time they are in their base personnel. They will do a 2 Gap front occasionally, with BOTH the RDT and LDT lining up over the tackles, but most of the time it's 1 Gap.

Notice the right RE is in between the tackle and guard. It's almost a 4-3 under with 3-4 personnel: #99 Aldon Smith is playing the roll of the Leo,#55 Amhad Brooks is playing the Sam, with #53 Navarro Bowman is in the role of the Mike and #52 Patrick Willis in the role of the Will on this play. Here Willis and Bowman are in the gaps between the T/G or C/G, rather than lined up directly over the G's as in a true 3-4.


Compare it to this, where the NT is over the C, and the RDT and LDT are directly over the T's, and the Mike and Jack are directly over the guards.

Madden says the 49ers run a "base 3-4" in the scheme section, but since when has Madden been overly trustworthy on football issues? They're wrong on that one, as the 49ers are rarely lined up in a true 3-4 front.
