Can someone please explain to me how the Jets are gonna beat the Steelers?

everybody is saying that the "jets are gonna win, they beat them once and they will beat them again" "we beat the Colts and the Patriots and have all the momentum", do they not realize that troy polamalu was out when they lost to the jets? That mark Sanchez overthrows almost every ball? That the Steelers have a higher caliber defense that's no where near the Pats and colts?
