If you really want a history lesson on the "air raid" you need to look back to the 60's for two dudes. Glenn Ellison and Mouse Davis. Glenn wrote the book, and Mouse took his system and perfected it
It was called the run and shoot. 4 and 5 wide and "spread" the Defense out and throw into the soft areas of the zone coverage. Once defenses started playing man to man, it got even easier until defenses had more speed than the wr's had. That created a problem. Most people don't realize that the Houston oilers regularly had backs rushing for impressive yardage in this "pass oriented" offense. Mouse coached guys like June Jones and Jerry Glanville. It's been bastardized, for lack of a better word into such offenses as the fun and gun (Steve spurrier), the spread, the air raid and the power spread.
Different philosophies to be sure but similar formations and results. A team with a great qb and some speedy pass catchers as well as a thumper at Rb can give you fits.
