I went ahead and spent the time tonight, finally, importing the game data from the 2021 and 2022 seasons (my first seasons running the site) so now all of the game data that I've ever gotten on this site has been completely imported into the current database, as well as all data that I was given when I acquired the site from Granger. Anything that's still missing is simply data that I never had access to.
I'll work on getting the dates from 1994-2020 inserted sometime during the next week or so. I want to give a little more time for folks to chime in here and correct me if I'm wrong about any of these year's start dates.
