2000: Marcus Fizer
A few years after the 2000 NBA Draft took place, Sports Illustrated looked back on this group and called it one of the worst draft classes of the modern era. The class featured on three All-Star selections in Kenyon Martin, Jamaal Magloire, and Michael Redd. But the worst selection of anyone in this group has to be forward Marcus Fizer, the fourth overall selection by the Chicago Bulls. Fizer never averaged more than 12.3 points per game at any point in his career, and after tearing his ACL in 2003, was merely a shell of himself.
By 2004, the Bulls made him available in the NBA expansion draft, where he was taken by the then-Charlotte Bobcats. Fizer only lasted one more year in the NBA, and was out of the league after five very forgettable seasons. He started just 35 games in his entire career — not exactly the type of production you’re looking for in a Top 5 draft pick.
