For sure. Look at Hoying & Germaine's numbers. By today's standards, they're very pedestrian, but at the time they were elite. Things definitely shifted to more QB-centric in the early 2010s. You could win NCs in the 1990s/2000s without a dynamic QB:
Colorado, Washington, Alabama, tCun, Tennessee in the 1990s all won with an emphasis on defense and the running game. In the 2000s, tOSU, LSU x2 and Bama in 2009 all won with the same model. By the 2010s, QB play emerged as the dominant piece of the puzzle.
But at the same time, a great QB could have certainly made those early 1990s tOSU teams much, much better. And I think if Cooper had just unleashed Germaine instead of splitting him with Jackson, our 1997 team would have been in the NC hunt instead of just a pretty good 10-3 team.
