The four-year extension, which was signed and announced on Tuesday, keeps the 30-year-old Wilson with the Seahawks through the 2023 season.
"Russ has been a huge factor in everything that has happened, and this allows us to stay on track with continuing to push to find that consistency," Seahawks coach Pete Carroll said. "Russell is a unique player, a unique competitor. It's rare the way he's just so consistently connected to competing and battling. To keep that factor as part of the program is just a real positive for our fans and for everyone."
In addition to topping Packers quarterback Aaron Rodgers' contract as the richest ever with a new-money annual average of $35 million per season, Wilson's signing bonus also sets a record. Rodgers was first in both categories at $33.5 million and $57.5 million, respectively, on the extension he signed last summer.
