(A-P) The Big 12 has long had a reputation for high-flying passing offenses. The spotlight has shifted a bit. Pass defenses are improving. And running backs are stealing some of the show. Last season, Oklahoma State’s Chuba Hubbard led the nation in rushing and finished eighth in the Heisman Trophy balloting. This season, Iowa State’s Breece Hall leads the nation in rushing and West Virginia’s Leddie Brown ranks eighth.
