His career has been defined by his ability as a return specialist and he will definitely bolster the Packers special teams unit.
Smith was selected in the sixth round of the 2018 draft and should be expected to fill the same role as a member of the Packers. Smith averaged 26.8 yards per kickoff return during his rookie season.
The move comes after Trevor Davis struggled against the Vikings, which could create a bit of competition. It's definitely an upgrade as the team deals with Darrius Shepherd's injury.
He doesn't have a whole lot of experience on the defensive side of the ball after logging just 74 snaps last year, but the Packers have been dealing with a ton of injuries over the last few years, so if that trend continues then Smith could see a solid chunk of playing time.
