Kenneth Walker III has changed the Chiefs’ math, and Mahomes is suddenly making defenses pay

The briefing

Running back Kenneth Walker III rushed for 117 yards on Sunday night against the Indianapolis Colts, becoming the first Kansas City Chief with consecutive games of at least 175 yards from scrimmage since 2005. Walker’s emergence on the ground has forced opposing defenses to respect the run, opening up the field for quarterback Patrick Mahomes to throw for 382 yards and three touchdowns in a 33-30 overtime win.
