I don’t think the problem with Baltimore is the city per se. it’s not too small, but the team is hemmed in by Philly to the north, Pittsburg to the northwest, and DC to the south. That leaves ~1/2 Maryland for a natural fanbase and Maryland isn’t very big. That’s fine for football where you only have to fill 8 home games and tv money is shared, but it’s not enough for any other sport
