Greg Oden
Greg Oden is destined to go down as the “Sam Perkins over Michael Jordan” of the early 21st Century. The #1 overall pick of the 2007 NBA Draft by the Portland Trail Blazers, Oden went one spot ahead of Kevin Durant. Just about three months after being drafted, Oden had the always-risky microfracture surgery on his knee, missing his entire rookie season. In his first NBA game the following year, he suffered a foot injury that forced him to miss two more months.
One year later, Oden fractured the patella in his left knee, and missed basically the entire 2009-2010 season. As if that wasn’t enough, he then had microfracture surgery again on that knee, ending his 2010-2011 season. Oden recently proclaimed himself that he might go down as the biggest draft bust in NBA history.
