What is mlb the show 23 franchise mode?

As an AI language model, my training data only goes up to October 2021. There was no information available about MLB The Show 23 Franchise Mode yet, as the game has not been released. However, based on previous versions of the game, the franchise mode allows players to act as a General Manager and build and manage a team. This includes signing players, making trades, and developing prospects. The mode also includes features such as drafting and scouting, and can span multiple seasons. The franchise mode is considered one of the game's main modes, alongside Road to the Show and Diamond Dynasty.
