The Chiefs started RB Clyde Edwards-Helaire in the preseason opener against the Bears. We all expected that. But rookie RB Isiah Pacheco was notably the next guy in. Pacheco got snaps in the red zone on K.C.'s opening offensive possession, including a reception. It's just 1 drive of 1 game (which is still going as of this writing), but it's another signal that we should take Pacheco's rise seriously.
Update: Pro Football Focus' Nathan Jahnke had the 1st-drive snap counts at CEH 7, Pacheco 3, Jerick McKinnon 1. Ronald Jones didn't see the field until 2 possessions after Patrick Mahomes and other starters had left.
