Oklahoma State senior basketball player Marcus Dove was named the Big 12 Defensive Player of the Year on Monday by the league's coaches. Dove, who shared the same award last season, is the second player in Big 12 history to win a major conference award on two occasions. Raef LaFrentz was the Player of the Year in 1997-1998. Dove frequently draws the role of stopping opponents' top scorers and has recorded 53 steals this season (tied for fourth in the league.) He is also in the top 10 in the conference for blocks with 34, including 21 in Big 12 play. Kansas State freshman Michael Beasley was named the league's Player of the Year and Freshman of the Year. It was the second straight season a freshman was named Player of the Year. Junior DeMarre Carroll was named the Newcomer of the Year, the second straight season a Missouri player has won that trophy. Sherron Collins (Kansas) won the Sixth Man Award, while Rick Barnes (Texas) is the Big 12 Coach of the Year.
