Texas A&M's Robert Williams burst onto the scene last year as a relative unknown in the NBA's eyes and was immediately viewed as a lottery pick.
His statistics were not eye-popping, but at 6'10" with a 7'5" wingspan and elite athleticism and shot-blocking ability, he had the attributes NBA teams covet in big men. He was raw but skilled enough that he got tagged with a high ceiling. He was a clear candidate to be one-and-done.
Then on March 21, Williams surprised many when he announced he would return for his sophomore season.
It's a path, however, that is not as risky as it was once viewed.
