Also, he's slated to earn $34.5 million in the first two years of the deal. The signing helps fill a massive hole at pass rusher.
Taken in the 2015 draft in the fifth round, Amos developed into a consistent safety for the Bears on a steadily improving defense. With Nick Perry's future still up in the air, and Clay Matthews set to become an unrestricted free agent, Green Bay's outside linebacker corps stands at Kyler Fackrell, Reggie Gilbert and Kendall Donnerson.
When the official details of Smith's deal are released, they will be added to this post.
Amos has ranked among the top 10 safeties in coverage grade each of the last two seasons, according to Pro Football Focus. Still just 26 years old, Smith has 18.5 career sacks in just 16 career starts.
Green Bay went 6-9-1 and missed the playoffs in 2018, marking the first time since 2006 that the franchise had failed to qualify for the postseason in back-to-back campaigns.
Amos is coming off a 2018 campaign in which he racked up 73 tackles, a sack, a couple of interceptions, a fumble recovery and nine passes defended. The team is holding on to defensive coordinator Mike Pettine despite making a head coaching change, and Smith gives Pettine a versatile, high-motor player to deploy in multiple spots.
The Bears will have a new strong safety next year - either a free agent, draft pick or incumbent backup Deon Bush.
Amos' presence in the Packers defense will work against the Bears in two ways. Free agency hasn't even officially begun, so who knows what else the general manager Brian Gutekunst will delve into.
