The Broncos have something the crow (whinny) about. They beat the Chiefs while S.F. couldn't. Years ago, 1983, when we lived in Miami, the hurricanes lost there opener to the Florida Gators, then went on tho win 11 straight and the NCAA championship.
UF fans had bumper stickers that said " #1 in the State, with the game score on it". (paraphrasing).
Don't be surprised if the Broncos do this.
