St-Juste started 42 games for the Commanders over the last three seasons, totaling just one interception but 31 pass break-ups over that span. Last season, he registered 71 tackles while playing in all 17 games and starting 14. The Chargers will bring him in to help bolster a secondary that seems likely to lose Asante Samuel Jr. to free agency.

St. Juste, Washington's top corner, will be a big loss against the run-heavy Falcons. His absence is a small upgrade for Drake London, who could see a target bump with Kyle Pitts (knee) sidelined. 

St-Juste will miss at least three games and could be shut down for the season after dealing with multiple concussions. The third-round rookie has appeared in nine games (three starts) but had been losing playing time with Kendall Fuller moving to the outside and Danny Johnson playing the slot. Washington activated CB Darryl Roberts off IR to take St-Juste's roster spot.

The deal includes a $1.069 million signing bonus. St-Juste (6'3/202) sports a long, lean frame that allows him to corral receivers at the line of scrimmage, as well as bring skill players down when tackling. St-Juste also timed a stellar 6.63-second three-cone drill at his Pro Day, an absurd number for a player his size. That flexibility does not always show up on film, though, in part because St-Juste's eye discipline can run hot and cold, leaving him slow to transition in some instances. The Football Team didn't have a pressing need a corner but extra depth at one of the most important positions never hurts. The signing of former Bengals corner William Jackson should keep St-Juste as a rotational player in his rookie season.
