One of the NFL's rising young offensive linemen won't hit the open market in 2019.
The 6-foot-1, 310-pound Mason, who turns 25 on Tuesday, was set to enter the final year of his rookie deal, which paid a base salary of $1.9 million in 2018. Mason, however, earned the pay raise because of his performance on the Patriots' offensive line, and sets himself up well for the next contract negotiations before he turns 30.
According to Over the Cap's position group salary rankings, Mason's new deal will rank among the league's top-earning right guards. The group is led by Dallas Cowboys guard Zack Martin's six-year, $84 million deal, which was signed in June.
Mason is widely regarded as one of the league's best run blockers and has become a mainstay on the Patriots' offensive line since entering the league in 2015 as a fourth-round pick out of Georgia Tech.
He has appeared in 46 games with 41 starts over the past three seasons, including 31 starts at right guard since the 2016 season.
