Webber played the point guard position and was the 2001 Mid-American Conference Men's Basketball Player of the Year.
[5] His 1996–97 junior season teammates included Shane Battier, who was a class ahead of him and classmates Javin Hunter and Mike Manciel.
[6] That team was the two-time MHSAA Class B defending champion and had climbed into the top 10 in the USA Today national poll prior to an injury to Battier and two subsequent losses.
[10] He described the pressure of being Chris' younger brother as having a severe impact on his mental state: “I can remember being in my house after another bad game during my junior year in high school, when I told God not to wake me up in the morning,” David said.
“I was praying all night, for hours, saying, ‘God, please don’t wake me up.’ “I felt a lot of pressure and I didn’t feel like I could take it anymore.”[11] Webber was only the third leading returning scorer (10.1 points per game) for the team that the USA Today described as "Favorite for fourth consecutive Class B title" when ranking them 15th in the preseason.
[12][13] In fact, he averaged 20 points over the first six games before focusing more on his role as the floor general because he felt the team had more success with him scoring less.
[5] Following the season, he earned Class B Second Team All-State recognition from The Detroit News and an All-USA Basketball Honorable Mention by USA Today.
[24] It was also the second-highest point total (highest in regulation) of the 1999–2000 NCAA Division I men's basketball season, trailing only 61 by Eddie House in double-overtime for Arizona State against Cal.
[28] He led the MAC in scoring (18.4 ppg) for the 2000–01 season and was the 2001 Mid-American Conference Men's Basketball Player of the Year.
[37] Webber attended the October 2002 Sacramento Kings training camp when his brother, Chris, played for the team[38] and survived the first cut.
[39] However, in late October, he was released along with Jason Sasser and Corsley Edwards when the Kings reduced their roster to 14 players.
[42] At the team's 16-man training camp he was vying for the point guard position against Andre Smith, Kareem Reid, and Jaquay Walls.
