Rivalry rematches are always tough. I don't cared what happened in SF, the 49er's can possibly win this game. I don't see the niner's losing by more then 3. In the 1998 the Broncos stomp the Chiefs 31-6 in Arrowhead. In the rematch game, the 12-0 Broncos needed a late touchdown to beat the Chiefs 34-30 at home.
