Kevin Durant immediately comes to mind when thinking about this list, and arguably, he could be considered the top one-and-done prospect ever. The versatile forward looked to be an entirely different beast in college and carried that momentum to the NBA, where he immediately became a top player. At 36, Durant continues to prove to be a top talent in the league, with multiple accolades under his belt, including two NBA Championships, two NBA Finals MVPs, and an NBA Most Valuable Player award.
