The success of the NCAA Blitz, a.k.a. America's Fire Zone, like any other Blitz or Fire Zone, is predicated not so much on the schematics of the play as much as it is on the fundamental techniques executed by each player. I have talked about the "Run to Daylight" technique of the playside DE (F in the diagram below) here in a previous post. Manny Diaz refers to this Fire Zone as Scrape, and I will talk about the "Scrape" technique of the Mike LB that is essential to the success of this play.
