WR · Los Angeles Rams vs Denver Broncos · 64 graded snaps
Replacement
Mumpfield delivered late-game vertical fireworks highlighted by a 48-yard touchdown, but a quiet early volume and perimeter blocking lapses held his overall grade to 69.5.
Mumpfield drove his 72 receiving facet grade primarily during a fourth-quarter surge, highlighted by a 21-yard sideline grab (Q4 04:16) and a 48-yard go-route touchdown where he stacked his defender vertically (Q4 03:46). Earlier in the contest, he contributed through effective clear-out stems and drew a 13-yard pass interference penalty on third down (Q2 11:03). However, 53 neutral snaps limited his upward momentum, while coverage breakups on quick out routes (Q2 13:24 and Q4 00:42) chipped away at his receiving grade. His run blocking also dragged the score down (58 facet grade), notably when he failed to sustain a perimeter stalk block that led to a defensive stop (Q4 05:43).
