AMES, Iowa (AP) – Iowa State will face by far its biggest test yet on Friday night when it hosts second-ranked Oklahoma State in a rare nationally televised game for the Cyclones.  Oklahoma State is averaging nearly 52 points a game, which ranks second in the nation, and last week it scored 49 points in the first half of a 66-6 drubbing of Texas Tech.  Iowa State coach Paul Rhoads says the Cowboys offense might be the best he’s seen in his coaching career. Oklahoma State quarterback Brandon Weeden leads the Cowboys with 3,635 yards passing and 31 touchdowns.
