Straight-line speedster with a fireplug build who needs to close the ability gap between when the ball is in his hands and when it's not. Duvernay is a challenging study because he carries long speed but he's not a ball winner. He's a slot receiver with tight hips and below-average routes but has outstanding hands and uses power to add yards after catch. The pieces don't quite fit together, but great hands, YAC and speed are traits teams might look to mold. He's not a classic developmental prospect but could become one if a team has a plan for him and can improve his routes.
Productive outside receiver with great size and ball skills, but below-average speed. May need to find an offense that allows him to work downfield, where size overrides quickness once the ball is in the air. He missed a chunk of 2019 due to a lingering hamstring issue, but looked fairly pedestrian against LSU's talented cornerbacks. He should work well against zone, but needs to play stronger to battle back against the contested catches he's going to see. Johnson may need a more limited route-tree that allows him to open up his stride and exploit size mismatches down the field.
