He comes off a year in which he racked up a career-best 53 tackles to go along with four quarterback traps. 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.
According to Mike Renner of Pro Football Focus, Smith led the NFL in sacks and quarterback hits on third down with 17 last season.
"Amos is an excellent safety who's been great for Chicago over the past couple of seasons", The Ringer's Robert Mays writes.
Both additions help the Packers at arguably their two biggest weak points on the entire roster. Also, he's slated to earn $34.5 million in the first two years of the deal. The money Smith got from Green Bay was too high for Baltimore to consider matching.
Needless to say, it's probably killing Thompson (who is now in a Senior Advisor role with the Packers) inside to see the team he was general manager of for so long hand out $183 million worth of contracts before free agency and the new league year officially open on Wednesday.
There's no question the Packers defense was upgraded with just two huge moves. That team's second-round pick in 2015 has been a 16-game starter each of the past three seasons and over that span has totaled 16.5 sacks, nine passes defensed, four interceptions and a pair of fumble recoveries.
