@slattimer and other actual experts know the true ins and outs of "Air Raid," but yeah Nebraska is very leery of a heavy passing attack which is I think what most people think about when they hear Air Raid.
I don't think it's much of a mystery though.
1. Our great teams of the 80s-90s were based on rushing the ball and recruiting linemen/RBs/QBs who were suited for that style
2. Osborne has told the public over the years that the midwest weather plays a part in leaning on the run game and many fans take his words as gospel
3. When Pederson pulled the Great Faceplant of 2003-04 we were all told that Callahan's WCO passing attack would modernize Nebraska football and everything we ever thought about being a physical rushing team was old fashioned and silly. When that turned out to be a debacle, people naturally went back to what was known and comfortable - wanting to run the damn ball
4. More recently, it seems clear that recruiting traditional NFL style LTs and QBs to NU is extremely difficult
At this point, I think any sane Husker fan realizes we need to have balance, but I'd rather try to be more focused on the run game than a heavy passing game. I also don't know shit about Xs and Os so the surface level is about as deep as I go haha.
