Week 2 Elo movers: Bills up 17, Lions down 17

Buffalo Bills rose to 1612; Detroit Lions fell to 1519.

Elo moves after every game: the winner takes points from the loser, more for an upset and more for a big margin, scaled by K = 20. A swing of 17 is a large one-week move; typical is 10 to 20.

Ratings feed next week's numbers directly, so these moves are already in the Predictions page. Elo alone trails the market over the long run, which is why The System weights it a quarter, but it is the part of the forecast that explains itself.
