I'm sorry -- did you say they've overtaken every team in the SEC defensively? Or overtaken everyone in the sec overall? (with the "possible" exception of Bama)?Not sure why so many here believe Riley/OU must win one in 2021 or else they never will. The Sooners will just keep improving under Riley and his coaching staff, especially defensively, where they've already overtaken every team in the SEC with the possible exception of Bama. And they'll have the benefit of having the top QB recruits in the nation for at least the next three years.
Having said all that, I have little doubt that the team that wins the most NCs over the next 10 years is the Alabama Crimson Tide.
