Salary cap league (1 Viewer)

[tms298]

Does anyone know a site that hosts a game where you have a fixed amount of $ to spend on players at the beginning of the year, but if the salary (value) of a player you own has goes up (or down), you can sell that player and spend that entire player's value on a new player? Most that I have come across allow you to sell and get whatever you had paid that player back, but I would like one that mimics the stock market.
