Week Eight: Seattle Seahawks at New Orleans Saints – Game summary
Over one and half year after Super Bowl XLIX, the Seahawks were trying to get their revenge against the Patriots after the heartbreaking interception. They successfully got their revenge by stopping the Patriots from getting into the end zone, and won the game 31-24. The Seahawks were the only team to defeat the Patriots under Tom Brady during this season (their one other loss, against the Buffalo Bills in Week 4, happened during Brady's suspension for the Deflategate scandal). This also marked Pete Carroll's first game in New England in 17 years after he got fired from the Patriots organization.

They only managed one sack on the final play in the third quarter, ending a streak of 10 consecutive quarters without a sack.
