The Washington Football Team signed Chase Roullier to a new four-year contract Saturday, keeping the anchor of its offensive line under contract through 2024. The deal is worth $40.5 million with $19 million guaranteed, according to a person with knowledge of the contract, which makes him the NFL’s 10th-highest-paid center by average annual value, according to OverTheCap.com.

After Coach Ron Rivera was hired on New Year’s Eve 2019, he said he wanted to spend the 2020 season evaluating the roster he inherited before committing to players for the long term. That stance, in part, led to trades of left tackle Trent Williams and cornerback Quinton Dunbar.

Now, a little over a year later, Rivera has locked in a key piece of the offensive line. Since Roullier, a 2017 sixth-round draft pick out of Wyoming, became a full-time starter in 2018, he has started 45 of 47 games — including all 15 this year despite dealing with a knee injury.

The biggest question on the offensive line remains right guard Brandon Scherff, the perennial Pro Bowl selection who received the franchise tag in the offseason. Scherff was the fifth overall pick in 2015, and he has been adamant since last season that he wants to remain with Washington. Under franchise tag rules, Washington cannot begin negotiating with him until after Sunday night’s season finale at the Philadelphia Eagles.

Washington’s game against the Eagles could offer a peek at the offensive line next season. Right tackle Morgan Moses and left guard Wes Schweitzer are under contract through 2022, and they figure to have a fair shot at maintaining those roles. The other question is left tackle, where Cornelius Lucas has been solid filling in for injured starter Geron Christian. The spot could feature internal competition next season among Christian, Lucas and 2020 fourth-round pick Saahdiq Charles.

But on Saturday, Washington solidified center for the foreseeable future, and rookie defensive end Chase Young was thrilled.

“Ayeeeeeeeeeee!!!!!!!!!!” he wrote on Twitter.

“[Roullier] has been a steady presence and leader on our offensive line all season,” Rivera said in a statement. “He is a great teammate and does everything the right way. We are glad to be able to reward a player who has spent his entire career here. He was well deserving of an extension, and I look forward to continuing to coach him as we work towards sustained success here in Washington.”
