The Chiefs still don't seem comfortable using Clyde Edwards-Helaire in most third-down situations, and until they do, the backfield is going to be more of a committee thing. But don't ignore that Edwards-Helaire has three touchdowns in three games.
The Chiefs seeming don't trust CEH in certain situations, and that was also clear last season in the playoffs when McKinnon stood out. McKinnon could very well still be on your waiver wire and is worth a pickup and a stash on your bench. CEH does seem to get the goal line carries, but the story said you can't count on him to keep up his current TD pace.
