The spreadsheet of each team's all-time record against all other teams, through 1989, has been posted on the league blog. You can view it here:

I will update following the 1990 season and post some notes and observations as well.

I decided to post the results through 1989 because the league reached a unique mileston that season. That marked the end of the fourth rotation for non-conference games—that is, every team in the American Conference had faced every team in the National Conference four times. The 1990 season marked the beginning of the fifth rotation.

I hope you will enjoy seeing how your team has fared against other teams in the league over the years. If you see any mistakes, please call them to my attention.

Thanks so much for doing the spreadsheet. If I was tracking it, I'd have to type out a post because I get flustered trying to work with office software.

I forgot how bad that Houston team was before I rebuilt it.

Yeah, I still have 11 players on the roster from your era. Doing my best to keep it rolling.
