So I put this out there:
I haven't done the research (yet) but it feels like when Alex Smith rushes the ball well = Chiefs win

I talk about "getting back to the 2013 Chiefs" because Alex Smith rushed for 431 yards that season. The Chiefs seem to play better when Alex rushes the ball well.
So far this season, the stats bear that out. Via Pro Football Reference:
During the Chiefs first six games in which they started 1-5, Smith averaged just under 20 yards rushing per game.
