There was a period of time where there was a "theory" that defenses like the 3 - 3 - 5 and the 4 - 2 - 5 were going to end the need for a nose tackle. However as recent years has proven the NFL and B1G and SEC teams are largely returning to, or have never stopped, using nose tackles (though that name isn't actually valid because the 0 - 3 tech is what we are really doing now). There may be schemes that are in incorporated in general defensive styles that use less 0 - 3s but they all realize that unless you are in the MW or possibly the Big XII, you are going to face opponents where you need one.you do realize some defensive schemes do not require some fat short guy to 2 gap.. lmao
That situation never even ever began to occur in the B1G especially nor the SEC to a lesser degree.
