Season so far
It is still very early in the season for Ko Kieft, who has appeared in just one contest so far in 2026. Across 35 snaps in Week 3, he recorded a net-negative 58.9 overall grade that placed his performance in detrimental territory. His grade was heavily dragged down by his primary role on special teams, where he posted a 57.7 facet mark over 33 snaps. A difficult first quarter proved costly, as he lost outside leverage on coverage, failed to sustain a wedge block, and was sealed inside on an 86-yard punt return touchdown. Kieft did flash some utility on offense with solid run blocking across two reps, alongside a shed to assist on a kick tackle, but it was not enough to overcome his coverage breakdowns.
