Save money in Franchise mode:
-----------------------------
Release a high paid player to free agency, then offer them a new contract. Their 
asking price may be lower than what you were already paying them. This could 
save your team millions of dollars. However, sometimes your players will demand 
more money after you release them -- so make sure to save the game before 
attempting this.
