@Brooks, Can you add new teams to the game or can you only rename teams?
I ask because Kennesaw State is moving to FBS in 2024. Would we be able to add them to the league? Or would we have to replace another team in order to have them?
I guess what I am asking is the number of total teams in the league absolute.

You can add new teams, but only via modding the teams.xml file (see mod forum for examples of people who are working on various formats) There is no way to "add a team" in game, only realignment of existing teams to various conference formats.
