Professional career
The Seattle Seahawks selected Britt in the second round of the 2014 NFL Draft. Britt won the right tackle job in training camp in 2014, and started there in the opening game of the season against the Green Bay Packers. Britt would start all 16 regular season games at right tackle for the Seattle Seahawks, as well as their divisional round playoff game against the Carolina Panthers, before missing the NFC Championship game with an injury. He was one of the worst pass blocking tackles in the NFL as a rookie, according to PFF. The Seahawks finished the season with a 12-4 record for an NFC West pennant, but lost to the New England Patriots in Super Bowl XLIX. After a poor showing at right tackle in the first preseason game of the 2015 season, Britt was asked to change from RT to LG. Britt was among the least effective pass blocking guards in football to start the season, but has showed improvement. After being ranked 49th in pass protection, during weeks 5–10 he was ranked 33rd and weeks 11–13 he was ranked 27th. His run blocking became better as well. He started all 16 games at right guard. In the 2016 offseason the Seahawks moved Britt again, this time to center. Pete Carroll stated that they had this move in mind when they first drafted him in 2014. For his efforts in the 2016 season, Britt earned recognition as a Pro Bowl alternate at center. On August 17, 2017, Britt signed a three-year, $27 million contract extension with the Seahawks. On October 29, 2019, Britt was placed on injured reserve with a serious knee injury. Britt was released by the Seahawks on April 27, 2020.
