This is BTB, and we're here to talk football. Free Agency began at 4PM Tuesday, and we've once again dusted off our Economics degrees. For now, it's X's and O's for me, and any of you that choose to come along. Most of us know that our Dallas Cowboys currently employ a 3-4 base defense. But how many of us actually know what it's supposed to do? Fear not. It's very common to be unfamiliar with the 3-4 as a whole. Whether you've just recently gained interest in the inner-workings of football, or poured hours into understanding the schemes of the early-90's dynasties, the 3-4 is unfamiliar territory. What doesn't help is that our coaches make little effort to divulge their strategies to the public (and for good reason), and our owner freely divulges information, albeit through an uncrackable cypher.
