Talk Fantasy Football

Has anyone tried to tackle this yet? I envision a list of stars available in the league, the ability to hire one onto your team (and prevent other teams from hiring them), and calculating the ongoing costs after each game.

No, although I have been contemplating it. A couple of coaches in my league want to use rostered stars.
The automatic Treasury calculation would be good, but think it needs to be expanded to include other income and outgoings given that there are multiple options now.
