ATLANTA (AP) -- A day after his team lost in the Super Bowl, Seattle Seahawks defensive coordinator Dan Quinn agreed to a five-year deal to become the Atlanta Falcons coach, a person familiar with the negotiations said on Monday.
The person spoke to The Associated Press on condition of anonymity because the deal has not been publicly announced by the team. The Falcons are expected to introduce Quinn as their coach on Tuesday.
The Falcons exercised patience while waiting for Quinn, who could not be offered a job until after Seattle's 28-24 Super Bowl loss Sunday night to the New England Patriots.
Quinn, 44, helped Seattle reach back-to-back Super Bowls. Seattle beat Denver in last year's championship.
He will replace Mike Smith, who was fired following a 6-10 finish in 2014.
Quinn's strong record in his two years with Seattle won over the Falcons, who have struggled on defense while finishing a combined 10-22 the past two seasons. The Falcons allowed the most total yards and yards passing in the league this season.
The Seahawks led the NFL in scoring defense, total defense and takeaways while winning the Super Bowl last season. Quinn's defense shined in the Super Bowl win over Peyton Manning and the Broncos. He previously was defensive line coach for the Seahawks, 49ers, Dolphins and Jets.
Seattle ranked sixth in total defense this season.
