Cap allocations rule explanation:
In case you don't realize, you aren't required to sign everybody you drafted today. If you don't want to allocate cap to a player then don't and simply drop him from your team when it is unlocked.
- Salary cap will be based on years and the cap will be 40 years. After the draft is complete you will assign years to your players. The total of all players combined on your roster cannot be greater than 40 at this point in the off-season.
- After this point free agency begins. Teams may sign players to multi-season contracts if they have the cap space. If they do not have cap space than can sign players to one year deals; such a player cannot be extended in the off-season.
Also, if you do allocate all your cap you can still sign FA's, but the player you release to sign the new guy will still count against your cap. The next guy you sign can only be signed to a one year deal if you're over cap and will be unrestricted at the end of the season.
