19. Kenyon Martin (2000):
In what turned out to be a rather brutal 2000 NBA Draft, Kenyon Martin was the consensus top player among a group of talented but questionable prospects. Martin stood 6’9 with a sculpted 230lb-frame, but was much more of a high-energy defender who could pull down rebounds with the best of them and block shots at the peak of their trajectory. But as far as an offensive game, Martin was still scratching the surface of understanding how to use his strength and athletic ability to abuse guys down in the paint, and his ability to shoot the ball from anywhere outside the paint was easily his biggest weakness.
And, of course, that’s not even mentioning the gruesome leg injury he suffered less than four months before the NBA Draft, which ended up sapping away much of the athletic gifts that made him a coveted prospect.
