From the video
there's a real chance that DS becomes so obviously their their best separator and he's somebody that Mahomes needs out there on the field... he's their best man coverage beater by far. It's not even close between him and Rashid Rice.
STACKED’s take
Chiefs trade-deadline add; elite separator but acclamation timeline uncertain.
Downs was acquired by the Kansas City Chiefs at the trade deadline for a fourth and fifth round pick and becomes the Chiefs' best separator and man-coverage beater. He is one of the better separators in the league and very good against man-to-man coverage, offering something the offense lacked. While acclamation may take time (DeAndre Hopkins comparison), if he's locked in and ready, he could be fantasy productive, especially with play-action opportunities built off Kenneth Walker's run game establishing the threat. The source notes Downs' talent is undeniable—a 25–26-year-old shouldn't suddenly fall off—and Andy Reid has a track record of scheming up small-bodied receivers like Xavier Worthy for success. Downs is the clear man-coverage advantage over Rashid Rice. However, the source emphasizes uncertainty: Downs has not played well this year in Indianapolis (Keenan Allen has outplayed him), and there is a real chance acclamation takes time to materialize.
