BIOGRAPHY: Has decided to go pro, along with teammate and twin brother Robin, following his sophomore season. Both have given up their final two seasons of eligibility after hiring agents. Brook's decision to test the NBA waters may have been influenced partly by his play in this season's NCAA tournament - he averaged 20.0 points and 5.3 rebounds, but the Cardinal were ousted by Texas in the South Regional semifinals. In his brief college career, Brook averaged 16.0 points and 7.1 rebounds, blocked 101 shots and shot 48.0 percent from the field in 53 games, including 43 starts. Brook, who missed the first nine games this season because he was academically ineligible, scored in double figures in 41 contests, including a career-high 31 points in a win at Washington in January. Despite playing just 21 regular-season games in 2007-08, Brook was a first-team All-Pac-10 selection after finishing fourth in the conference with 18.9 points per game, trailing only highly touted freshmen O.J. Mayo of USC and Jerryd Bayless of Arizona, and California sophomore Ryan Anderson. As a freshman, Brook was Stanford's third-leading scorer with 12.6 points per game, and tied Lawrence Hill for the team lead with 6.0 rebounds. In just his fifth start, Brook posted the Cardinal's first triple-double since 1985 with 18 points, 11 rebounds and a school-record 12 blocked shots during a win over then-No. 25 UCLA in January 2007. That helped him earn All-Pac-10 freshman honors, but Brook decided not to enter the draft at that time.
