i'm not sure what football you've been watching but here are few if any oldschool power i running football teams anymore. every school and nfl team runs spread concepts and power concepts. that brand of "real football" is gone so its gonna be a long wait for you.
Spread concepts were used by Fulmer too. Running an NFL style offense really just means you're not running a primarily zone read/option offense.
There are NFL teams that run heavy spread(Packers, Pats, Cards), there are NFL teams that are run heavy/heavy personnel(Titans, Cowboys), there are teams that mix it up(Steelers), etc.
I don't know why it's fallen out of favor so much in the college ranks. I suppose just taking advantage of all the athletes we have now'adays. But you still have highly successful programs like Stanford, Michigan, Wisconsin, Iowa(eh, their success comes and goes, but whatever), Michigan State, Bama isn't too far removed from winning championships with pro style offense, Mark Richt has incorporated more spread in to his offense in recent years, but he had a lot of success out of pro style, etc.
I'm fine with either offense personally, both can win championships.
