You can also buy teams with enough flex points, so if we get some good players going, someone could buy a team and work players from here in depending on if they can cut the mustard. There are all sorts of things like seat upgrades, adding more sections, consessions, ticket prices, and of course fans coming to see the product.

But that will take some time and flex points.
