2016 was just six years ago. There were games that weren't a lot of fun, but I think people forget how bad it was before this run of 10+ win seasons.
2017 had the embarrassing loss to Miami and then the collapse against Stanford.
2019 had the blowout to a bad Michigan team.
I'd rank 2018 and 2020 over this year, but that's about it in terms of recent seasons.
