Slender-framed slot target with field-stretching speed and talent to work all three levels of the field. Allen has elements to improve on as a route-runner, but his sudden acceleration and top-end speed create separation on a consistent basis. He’s a menace on go routes and slot fades. He has adequate hands but will end up on the wrong side of contested catches. Elusiveness after the catch could create additional value for Allen, who could become a productive playmaker as a middle-round pick.
Caldwell is a developmental prospect with enticing traits and a need for better fundamentals. He’s a long-strider with the ability to create separation vertically, but his route-running is underdeveloped and he needs tutoring on how best to set up routes. Caldwell’s contested-catch rate is disappointing for a player with his size and ability. Coaching should help create more advantages in that area, but he might need to ratchet up his competitiveness on 50/50 balls, as well. His production at Cincinnati won’t excite, but his NFL Scouting Combine performance shows there could be more upside to unlock, which makes him worthy of a middle-round pick as a backup “Z” receiver.
