Mike Reiss of ESPNBoston.com reports that the deal will pay Mankins a $1.5 million base salary this year, which means Mankins will make $21.5 million — or more than twice as much as he would have made if he played this season on the one-year franchise tender, which would have paid him a little more than $10 million. However, even though Mankins will receive twice as much money as he would have on the franchise tag, he’ll cost only half as much against the Patriots’ salary cap because the $20 million signing bonus is prorated over the six-year deal.
In future seasons, Mankins will have a base salary of $3 million in 2012, $6 million in 2013, $6.5 million in 2014 and $7 million each in 2015 and 2016.
Mankins can also earn a workout bonus of $250,000 a year, which would bring the total value of the six-year deal to $52.25 million. The deal makes Mankins the highest paid guard or center in football.
