What is clear in the wake of the Chiefs waiving Emari Demercado is that they don’t really have another player that qualifies as a passing-down back besides Walker without squinting. The other backs they kept are Emmett Johnson, a Day 3 rookie, and Brashard Smith, a gadget player without enough size to really block. Perhaps the Chiefs will address this in street free agency ahead of the season, but as things stand, it certainly seems like Walker will be involved on all three downs.
