Create Cap Space
When you start a Franchise mode with any team, you can create more cap space by releasing a player and then signing him back for less money and more years. You can do this untill they stop taking cuts. Players 27 and older can be re-signed for up to 7-year contracts and take cuts, players 25 or 26 years of age can be re-signed for up to 6-year contracts and take cuts. Players 25 and under can be up to a 5-year contract and take cuts. Players will not except offers unless the years are good (not too many years or not too little) and the cut is not too much. They can take cuts from $500k a time to just $50k a time, depending on how much they want, how old they are, and how long the contract length is. After the first year is over, this will not work as players will want more every time they are released.
