While the draft order is set after the Super Bowl, the official number of picks for the draft as a whole and for each team isn’t set till the 2018 NFL Draft Compensatory Picks are announced. Only 32 total Compensatory picks can be given out and are determined by the NFL Management Council given based on free agents lost compared to free agents signed in an overly complicated formula.
Compensatory Picks have long been crucial for NFL teams who have lost key free agents and used this extra picks to add talented players including in the 2016 draft where the Dallas Cowboys used a Compensatory Pick they gained to take Dak Prescott.
Only four 3rd round picks were awarded this year compared to the 11 picks being awarded in last years draft. The Cincinnati Bengals, Green Bay Packers, Dallas Cowboys and Oakland Raiders are tied with four total picks each for the most out of any team awarded.
For the longest time teams were locked into their Compensatory Picks and not allowed to trade them but recent rule changes make the 2017 NFL Draft the second year teams can trade their Compensatory Picks.
