Oklahoma City Thunder all-time draft bust starting 5

Shooting Guard: Terrance Ferguson

In 2008, California guard Brandon Jennings became the first top-tier high school basketball player to skip college to instead play professionally in Europe for a season before he was draft eligible. It's hard to say it helped his draft stock, as he had a shot to go in the Top-3 if he had dominated in college, but he still went No. 10 overall in the 2009 draft and paved the way for other American players to take a similar route.

Not many prospects followed that path over the ensuing decade, but a few did, including a high-flying shooting guard named Terrance Ferguson. Rather than play for either Alabama or Arizona, two teams he initially committed to, the Texas basketball star elected to play for a year in the Australian NBL for the Adelaide 36ers for the 2016-17 season.

Ferguson did not gain much from the experience in terms of draft stock, but there was still an air of intrigue around Ferguson heading into the 2017 NBA Draft. Would the team that ultimately drafted him get a bargain because Ferguson had obscured his development by playing in such an unfamiliar league?

The answer was an unequivocal no. The Thunder took him with the 21st pick in 2017, one pick ahead of Jarrett Allen and two ahead of OG Anunoby. Ferguson was never able to find his footing in the NBA, as he was a shooting guard who couldn't really shoot and didn't have the on-ball skills to be a combo guard. He was a decent enough defender due to his athleticism and motor, but whenever he stepped on the court the Thunder's offense cratered. Ferguson would last just four seasons in the league before moving back overseas to continue his career.

Should have drafted: OG Anunoby
