Army, Navy and the Air Force still run the flex-bone/triple option. Georgia Tech was running it recently as well. I still feel in the end superior athletes (both mentally and physically) and coaching is what ultimately wins football games no matter what type of scheme you're trying to run.
To a point. If that were the case we'd see a much wider range of schemes at the top, but nobody is running triple option or the air raid at the top - if scheme truly didn't matter, some probably would. If you've got the athletes and coaches you can do well with anything, but scheme can limit your ceiling.
And more importantly, good athletes don't want to play in schemes that don't maximize their opportunities, and good coaches tend to innovate and wouldn't stick with a scheme holding them back. Osborne's offense changed pretty significantly over the years, and he made the call to change the defense when it was good but not good enough. Saban is always bringing in guys with new ideas.
