The Patriots locked up another core young player on Thursday night, agreeing to a three-year extension through 2020 for starting center David Andrews, a league source confirmed.
Financial details including guarantees and signing bonus are not yet known, but the contract has a base value of $9 million and a maximum value of $11 million, according to reports.
Andrews, who turns 25 in July, has been one of the Patriots’ most dependable players in his two NFL seasons. An undrafted free agent out of Georgia in 2015, Andrews not only made the Patriots but held his own as a rookie while incumbent Bryan Stork dealt with injuries.
Andrews played in 14 games (with 11 starts) as a rookie, then started all 16 games plus three playoff games last year as the Patriots won the Super Bowl. Andrews played 1,359 of 1,363 possible snaps last season, beating out guard Joe Thuney for the most snaps played of any Patriots offensive player.
The Patriots now have four of their five offensive linemen signed for multiple years. Right tackle Marcus Cannon signed a new contract through 2021 last season, right guard Shaq Mason is under his rookie contract through 2018, and Thuney is under his rookie deal through 2019.
Only left tackle Nate Solder is in limbo as he enters the final year of his contract. The Patriots drafted tackle Tony Garcia in the third round of this year’s draft, potentially as Solder’s replacement.
Andrews was entering the final year of his contract in 2017, and would have been a restricted free agent next offseason. He received a $15,000 signing bonus coming out of college, and was playing on a three-year deal that paid him minimum salaries each season. Andrews was due to make $615,000 this season.
He becomes the second Patriots player this offseason to sign a contract extension before hitting free agency. Running back James White also signed a three-year extension last month before entering the final year of his contract.
But cornerback Malcolm Butler, who signed his one-year, $3.91 million restricted free agent tender, hasn’t been able to get a long-term deal that he finds suitable.
