Does anyone know any P5 schools that run the 3-4? Is this a unique defense and thus harder to prepare for or is it not all that unique and not difficult to prepare for?
Not really a unique defense, just under-utilized. If you have great LB's it's probably better to use the 4-3. Let your three best guys run around and tattoo people. If you have speed and athleticism, with decent size and depth on d-line you can run the 3-4. They are almost the same defense when its all said and done, because you will normally be rushing at least 4 in the 3-4 defense. Trading a bigger body for a faster body in the end.
