Ranking the 10 best CFB defenses ahead of the 2023 season

The spring has been spent breaking down which offenses (quarterbacks, running backs and wide receivers) will define the upcoming college football season, so it’s now time to look at what ultimately wins championships: the defenses.
The Georgia Bulldogs broke their 41-year title drought, then followed it up by becoming the first back-to-back champion in a decade, behind a stellar defense featuring a number of future NFL players.

Mykel Williams is coming off a minor foot surgery and will also be a big part of this group after leading the team in sacks last year. The Bulldogs are also hoping for development from the likes of Tyrion Ingram-Dawkins and Christen Miller.
