Warren's rookie numbers present an interesting puzzle. He finished TE7 overall in his first NFL season but only TE11 on a per-game basis at 9.1 points per game, and his ESPN receiver scores were near the bottom of the tight end sample—9th percentile in OPEN score and 8th percentile OVERALL—suggesting he struggled to consistently create separation against NFL coverage. At the same time, his PFF metrics told a different story: 75th percentile in YPRR and an 88th percentile YAC per reception, indicating that when he did get the ball, he did real damage. The 68th percentile route grade for a rookie is respectable and suggests the foundation is there for improvement. He also runs a high percentage of routes from the slot (68th percentile), which helps. The disconnect between the ESPN and the PFF productivity metrics isn't unusual for a rookie TE learning to navigate NFL coverage—the YPRR and YAC numbers suggest the tools are real.
