Couple caveats here. There are better teams in the second half of the schedule, so some of these stats may change considerably. Second, when comparing 2020 to 2019, I measured the 2020 stats by where they would rank last year. This year's rankings don't mean much given the staggered conference schedules.

Quick observations. Big improvements in scoring offense (+73) and third-down percentage (+105). Also much better in the red zone (+93) and FGs (+98). Our pass protection is much improved but still bad.
Our pass rush (-68) and rush defense (-46) are way down. Shaq and Rousseau are the big personnel losses there. Our pass defense (+30) and third down defense (+32) are trending up, likely due to a more experienced secondary. Our scoring defense is stable so far but will be tested in the weeks to come.
