Douby took a scholarship to Rutgers out of high school in 2003 and played three seasons for the Scarlet Knights, averaging 17.8 points-per-game, and shooting 47 percent from the field.
The sleek shooting guard burst upon the scene as a freshman in 2003-04, scoring 35 points in an NIT semifinals victory, while earning Big East All-Rookie and Met Rookie of the Year accolades. He had one of the best individual seasons in RU history as a junior in 2005-06 when he averaged 25.4 points-per-game and was recognized as the Big East Player of the Year. Douby scored 1,690 points, the sixth-highest total in Rutgers men's basketball history.
He made a school-record nine three-pointers to score a Carrier Dome opponent record 41 points at Syracuse on February 1, 2006. The Haggerty Award winner as the Metropolitan Player of the Year and an All-American in 2005-06, Douby is among the Rutgers career leaders in every offensive category.
Professionally, Douby spent five seasons in the NBA, being the last Scarlet Knight to be drafted in the first round in 2006 by the Sacramento Kings. Douby played professional basketball in multiple countries and had a successful international career after his time in the NBA in Turkey, China, and Spain.
Douby said that earning his degree was a promise that he made to himself at a young age when he accepted the scholarship to RU and a promise that he made to his mother on that day. Douby reflected on his time in Piscataway, being what he called “one of his biggest blessings in life”.
