Walker produced a 97th-percentile run grade in 2025, second-best among qualified backs, so the talent is real. The problem in Seattle was opportunity–221 carries, five touchdowns, while sharing the backfield with Zach Charbonnet. Kansas City represents a significant change in scenery: the Chiefs enter 2026 with 288 vacated RB carries, the most of any team in the NFL, clearing the runway for a genuine workhorse role. The concern is the blocking environment. KC's run-block win rate fell from 7th to 25th last season, and the team was a net loser in offensive line spending this offseason with no early-round picks. Creed Humphrey remains an elite center, but run blocking was a weakness last year and it really didn't get addressed. Walker's elite elusiveness (89th-percentile elusive rating, 88th-percentile broken-tackle rate) gives him a chance to generate on his own, which is probably why the Chiefs went after him. A high-upside RB2 some environment risk.
