They record these at coaching seminars either on campus or nationally and then high school coaches buy them so they can teach their players. Fans can buy them as well if you want to know more about what is going on in the game. Muschamp has one talking about secondary coverages that you can buy as well. Lawing is all about building a front 7 that can rush the passer and get off the field on 3rd down. It will be interesting to see what he does with Fowler this year I expect him to be in many different spots when we play Bama. I know some "fans" love blitzing but the big thing we want to do when it comes to rushing the passer is effecting the QB with just sending 4. Here is just a clip from Lawing's dvd on pass rushing. First few clips you see that when we were playing spread teams in certain games we had 3-3-5 Fowler at DE and using Powell as buck. Then they take Powell of and use Fowler standing up. I would assume a big part of camp on the defensive line was trying to figure out who would be that 2nd pass rusher on the Dline with Fowler. The options are McCalister Willis Ball and Powell.
