Great post above and you're right, the "air raid" isn't new at all. Leach made some tweaks through his mentor Hal Mumme back in the early 90's. Of note, I grew up in Lubbock TX and a Southwest Conference junkie as that was our "New York Jets" or pro football so to speak. Tech was everything to those in West Texas, even to this day. I'm very familiar with TCU and Sammy Baugh era. I played for Spike Dykes 90-94. We were defense heavy on that team, notables (Zach Thomas MLB, and Marcus Coleman DB, who most on this site will recall). Offense our RB was Bam Morris, so we had some talent.
Jack Pardee who was the HC at Houston also ran this type offense at that time called "The Run & Shoot". His QB was Andre Ware (Heisman Trophy and David Klingler who was 1st round selection I think #5 or #6.) Anyway, not new.
My reason for posting the video was educational only. Very good explanation of the Mike Leach coaching tree and his version of the "air raid" which has and will IMO be more prominate in the NFL in the years to come. The league is trending that way and most on this site are right, the true Leach air raid wont work as he runs it in college. That said a lot of teams and coaches (Kingsbury) will get more aggressive than what Any Ried is doing and make an impact that will eventually be a trend at the very least. I'm not advocating the spread vs conventional vs heavy run. Was nearly trying to give some sound insight and explanation of what this style offense really is which is more than a gimmick and some explanation with current teams that run it.
I'm a football junkie and love reading about the wishbone (Barry Switzer-OU), triple option (Georgia Tech/Navy). I think all these offenses are fückin great and with the right talent are effective. X's & O's with regard to football fascinate me. Appreciate your post again, brings back some memories.
EDIT: As noted in above post, KC, NO, Rams are a few teams similar. Kingsbury will be more aggressive version of those, time will tell.
