Oklahoma's Baker Mayfield is the unanimous pick as The Associated Press Big 12 offensive player of the year for the second time in three seasons, and Sooners linebacker Ogbonnia Okoronkwo is the league's top defensive player.

The playoff-bound Sooners have six first-team picks on the AP all-league team announced Friday. Mayfield, the AP player of the year and the Heisman Trophy favorite, was also the league's top offensive player in 2015. Oklahoma big-play receiver Dede Westbrook took the honor last year.

Iowa State's Matt Campbell was named the league's top coach. The Cyclones have their first winning season since 2009, including wins over top-five teams Oklahoma and TCU.

West Virginia junior quarterback Will Grier, a former Florida transfer, was named the league's top newcomer.
