Each team received 4 contracts to use, EVER. 1-3year, 1-2 year, 2-1year
The 3 year will protect one player from 3 offseason rolls. Basically, if you use it, you are locking the guy in at his end of year stats for the next 3 seasons. He cannot age, gain or retire.
All contracts must be used on ORIGINAL ROM PLAYERS
Once you have used your 4 contracts, they are gone forever.
A player can only accept one contract in his career. Consider all players virgins. One penetration and it is gone forever.
Contracts are not tradeable. Contracted players are tradeable, and their contracts carry over to the new team.
