How many times have you been to a clinic and heard a speaker talk about America's Fire Zone? Too many times, probably. It's not like there are only a limited number of pressures that you can run (Blitzology with proof of that on his site here). I will talk about America's Fire Zone, but I will use it as an example of how to make Fire Zone adjustments. Dick LeBeau refers to this as Strong Scrape Fire Zone in his 2002 Bengal playbook here.
