QB Dak Prescott’s Contract Dominates Cowboys 2021 Offseason - Jess Haynie, Inside the Star
Here's some more data supporting the premise that the Dallas Cowboys absolutely must get Dak Prescott signed to a multiyear deal, rather than tagging him, which would eat up an estimated $37.7 million of this year's cap.
This would be true any season but especially with the salary cap expected to drop this year. Usually increasing by about $10 million every year, the 2021 cap is projected to decrease from $198 million to around $175-$185 million this year as the NFL accounts for revenue losses during the pandemic.
