Ok, I finally went back and finished updating this chart I made near the ned of last season. It's the record of all playoff teams (plus a couple playoff contenders that just missed) against teams that finished with a winning record. I did it all by hand so let me know if I made any errors.
I'd also note that some of the games need asterisks, like the Broncos beating the Chiefs' backups and the Commanders beating Kenny Pickett.
