Douglas mirrors Johnston's movement and route style but lacks Johnston's tackle-breaking ability.

Quentin Johnston serves as a movement and route-running comparison for Caleb Douglas. Douglas's movement, route-running style, and head-ducking mechanics closely resemble Johnston's, to the point of appearing like an impersonation. However, Douglas is not the same tackle breaker Johnston was in college or the NFL, though Douglas is a better contested catch player and ball tracker downfield. Like Johnston, Douglas is very raw as a route runner and less explosive as a mover.
