Kansas City hadn't rostered a true fullback since 2022, so VanSumeren's permanent promotion to the 53-man roster in September 2026 says a lot about the Chiefs wanting to run the ball more physically. Special-teams coordinator Dave Toub has already praised him as a four-phase contributor, which suggests real coverage-team value beyond just lead blocking.
Strengths: Versatile enough to contribute on all four phases of special teams in addition to his lead-blocking fullback role.
Weaknesses: Fullback touches are rare in this offense, so his per-game offensive impact will stay limited even with a roster spot.
