Last season, per Sports Info Solutions, the Chiefs led the NFL in dropbacks with pre-snap motion with 546. Mahomes completed 336 passes in 489 attempts with motion for 3,389 yards, 1,219 air yards, 23 touchdowns, eight interceptions, and a passer rating of 109.9. Without motion, Mahomes completed 169 of 257 passes for 1,845 yards, 850 air yards, 10 touchdowns, seven interceptions, and a passer rating of 88.4. The Chiefs knew they didn’t have the kinds of receivers who could consistently separate without schematic help, so they gave them as much schematic help as possible.
