The way Florida State’s teams practiced in the 1960s was enough to impress a Marine Drill Sergeant. Take it from John Crowe and Dale McCullers, who lined up at linebacker and safety respectively back then. They and their teammates set the standard for how Florida State defenses should play. And their book, “FSU’s Sons of the Sixties: A Case for the Defense,” is a tribute to those guys who played their guts out, and how it formed a lifetime brotherhood. We invited John and Dale to talk about what it took to shut down opponents while building a tradition of stingy defense at Florida State. Though it’s been over 50 years, you may be surprised by how much of it is still relevant.
