Western Kentucky senior center Chris Marcus was left off The Associated Press preseason All-America team, which was announced Tuesday afternoon. Marcus led the nation in rebounding last season with 12.1 per game, but was listed only on the others receiving votes category. Were really proud that Chris is an All-American, WKU coach Dennis Felton said. Were really proud that we have an All-American at Western Kentucky. Marcus has been named to several other All-American teams. The APs first team, meanwhile, was made up of Dukes Jason Williams, Missouris Kareem Rush, Kentuckys Tayshaun Prince, Stanfords Casey Jacobson and Illinois Frank Williams. Felton said he thought that since all the first-teamers played in big conferences with plenty of television exposure, they probably had a step up on Marcus. Certainly, I think that when youre on TV a lot, youre exposed to more of the media members that are doing the voting, Felton said. The only other player from a mid-major conference to get votes was Dan Dickau from Gonzaga. Jason Williams, who led Duke to the national championship last season, was a unanimous selection and the first player on every ballot since 1996.Jason Williams was on each of the 72 ballots from the national media panel that selects the weekly college basketball poll, becoming the first unanimous preseason pick since Tim Duncan of Wake Forest five years ago. Williams averaged 21.6 points last season the first Blue Devil to lead the Atlantic Coast Conference in scoring since Danny Ferry in 1989 3.3 rebounds and 6.1 assists. He was the only player to rank in the top 20 nationally in scoring (15th) and assists (19th) as Duke won its third national championship. The top-ranked Blue Devils lost national player of the year Shane Battier and fifth-year forward Nate James, but Williams, who averaged 25.7 points in the NCAA tournament, will lead the way as they try to become the first team to repeat since Duke did it in 1992.Rush, the preseason Big 12 Player of the Year, was the second-leading vote-getter with 47, one more than Prince and two more than Jacobsen. The 6-foot-6 Rush led the conference in scoring last season with a 21.1 average. His run at national postseason honors was hurt when he missed seven games with a thumb injury on his shooting (left) hand. Prince, the Southeastern Conference Player of the Year, withdrew his name from the NBA draft to return for his senior season with the Wildcats. The 6-9 Prince belied his thin frame by playing at power forward last season and wound up a second-team All-American after averaging 16.9 points and 6.5 rebounds. Jacobsen is going to draw a lot of attention from opposing defenses this season as the only returning starter for the Cardinal. The 6-6 swingman averaged 18.1 points in a balanced offense as he became Stanfords first All-American. Frank Williams returns to the Fighting Illini after being selected Big Ten Player of the Year and a third-team All-American. The 6-3 guard averaged 14.9 points, 3.7 rebounds and 4.4 assists.
