1. Players that are cut or not tendered as RFAs and ERFAs are not counted.
2. Players earning low minimum salaries do not count.
3. Each player signed cancels out one player lost.
4. The round of the pick awarded is primarily determined by the annual value of the contract signed. Signed players cancel out lost players with equal contracts, then lower contracts, before canceling out higher contracts.
It should be noted that although the NFL makes public the basic rules above, even the NFL teams do not know the exact picks that they will be awarded. They have to make assumption based upon past history, just as I have done.
