Zion Williamson and the 20 best one-and-done players in college basketball history

Zion Williamson was one of the best players college basketball has seen in the past decade, but where does he rank among the greatest one-and-dones of all time?

Even though Duke didn’t make the Final Four this year, Zion Williamson had a historic year that ranks among the best of all-time in the one-and-done era of college basketball.

That should be all we see of Williamson in a Duke uniform with the star forward projected to go with the top pick in June’s NBA draft. Williamson is just the latest college star to become a part of the one-and-done era, but where do his accolades rank among some of the other college greats.

After doing some extensive research, we have identified the 20 best players to hit the college hardwood for only one season since 2000. A lot of potentially great players could have been a fit as one-and-done type talents, such as LeBron James and Kevin Garnett, but prior to 2005 high school players were eligible to jump right to the NBA.

The league negotiated an age limit with the union at that point, mandating that a player be one year removed from high school before they could turn pro, creating a massive influx of talent to the college ranks that would never have been seen in the modern era. Williamson’s talent alone helped him crack the top 20, but you’ll have to read on to see exactly where he fell.

We’ll begin our countdown with one of Williamson’s teammates, forward RJ Barrett.
