From the episode

Emmitt Johnson is producing at a starter's level as an RB2 as a rookie, which is big for the Chiefs because it means that as much as they love Kenneth Walker's achievements... when they have to bring in the rookie, to make sure that Kenneth Walker stays healthy... There's not a massive drop off.

STACKED’s take

Positive signalRole

Chiefs' backup RB producing at starter level, enabling Walker load management.

Pacheco (referred to as Emmitt Johnson in the source, likely a transcription error for the Chiefs' backup RB) is producing at a starter's level as an RB2 as a rookie, which is significant because it means the Chiefs can manage Kenneth Walker's workload and health concerns without a massive drop-off in offensive production or explosiveness.
