The question of what has gone wrong with the Florida defense of late is one with too many answers for a single article. The fact remains, though, that 2019 was the last time UF had a good defense, and as of this fall that’ll be five years ago.
One way to simplify things is to break down defense into two categories: efficiency and explosiveness. Efficiency is about how good the defense is on a down-to-down basis. Explosiveness is about how often a defense allows big plays and how big those plays are when they happen.
The measures of these that I’ll be using are success rate for efficiency and expected points added on success plays for explosiveness.
