From the video

He was third in ass, fourth in separation win rate... I think A tier is very fair.

A-tier target with high separation metrics and primary X-receiver role
The source ranks Romeo Doubs in the 'A tier' of waiver wire targets, citing his high separation win rate, top-10 status in advanced metrics, and his role as the primary X-receiver in the offense. While Mack Hollins' injury may have inflated recent numbers, the X-receiver role is historically productive in this scheme, though Drake Maye's tendency to spread the ball around could limit Doubs' individual ceiling.
