College football's top 25 future defense power rankings
The contrast between the LSU and Alabama teams that played for the national championship in January 2012 and those that captured the past two national titles isn't lost on anyone who studies college football.
Offense and quarterback play drive championship teams more than ever. But defense isn't an afterthought. While the 2020 Alabama offense and the 2019 LSU offense are among the best in college football history, the defenses ranked No. 7 and No. 11 in efficiency, respectively, in those years. Clemson's two recent championship teams ranked first (2018) and eighth (2016) in defensive efficiency. A degree of balance is needed, which offense-leaning title hopefuls like Oklahoma are aiming to achieve.
