Since Tannehill's injury-guaranteed $29 million 2022 base salary becomes fully guaranteed next March on the fifth day of the 2021 league year, Laremy Tunsil Jersey the deal is e sentially a three-year commitment even if his outstanding 2019 season proves to be an anomaly. , QB, Contract value:$50 million for two years ($25 million per year average)Contract guarantees:$25 million (no signing bonus)Fully guaranteed at signing:$25 millionEarliest realistic exit point:2021 ($25 million earned) Just as in 2018 when Brees signed a two-year, $50 million contract, he gave the Saints another break financially this time around. Brees' new deal is structured just like the 2018 contract. His $23 million roster bonus that was due on March 22 is being treated as signing bonus for salary cap purposes because it was fully guaranteed when the deal was signed. The roster bonus is prorated at $5.75 million on the salary cap through 2023. That's because of 2022 and 2023 contract years automatically voiding on the last day of the 2021 league year in mid-March 2022. Saints head coach Sean Payton anticipates the 41-year-old Brees will retire after the 2020 season.

Instead, Lawrence's third-year salary in 2021 was fully guaranteed last week on March 22 while Cooper's third-year salary in 2022 doesn't become fully guaranteed until the fifth day of that league year. In other words, the third-year guarantee for Lawrence vests a year earlier contractually than Cooper's. It wouldn't matter as much if Cooper had gotten the same $25 million signing bonus as Lawrence because he would be better protected from a potential release in 2022 than with his actual signing bonus. If Cooper isn't producing, the Cowboys can pick up $16 million of salary cap space by releasing him in 2022 before the full guarantee is activated.
