It's not usual for a seventh-round pick to have a realistic path to see the field early in the NFL, expect for special teams. But Anthony Johnson Jr. may be an outlier for the Green Bay Packers this year. Considering how much experience he has, his decent floor, and the depth at the position, it's not absurd to think the defensive back might end up starting games opposite Darnell Savage by the end of his rookie season.
The safety position is arguably a need since last year, when both Adrian Amos and Darnell Savage were entering contract years and there was no long-term plan behind them.
