3 players who made the wrong call by remaining in the NBA draft

The decision by the NCAA allowing players to go through workouts with NBA teams before deciding whether to return to school was a great move.

Allowing players to receive full evaluations certainly could assist in choosing the right path to further their career development. Most players not guaranteed to be a first-round pick returned to school, but that doesn't mean everyone made a wise choice.

Here's three players that will wish they returned to school when they are toiling on the bench somewhere next season.

Cheick Diallo, Kansas

Despite averaging just three points and 2.5 rebounds in 7.5 minutes of action per game, Cheick Diallo opted to remain in the NBA draft and not return to Kansas for his sophomore season. Scouts rave about Diallo's potential, but his inability to find floor time at the college level has to be a major concern. His 6-foot-9, 215-pound frame is currently nowhere near strong enough to play the stretch-four position in the professional game. If Diallo returned to Kansas, he would be one of the focal points for Bill Self's offense, and could post gaudy numbers in a weakened Big 12. With just three power forward prospects ranked in the top 15 for the 2017 NBA Draft by DraftExpress, Diallo could easily be a lottery pick next year. Instead he will hope to hear his name called in the first round on June 23.

Troy Williams, Indiana

Most people assumed Troy Williams would return to Indiana for his senior season, but the 6-foot-7 forward chose to remain in the NBA draft. If the athletic wing talent had a big showing at the scouting combine, his stock was sure to rise into the early second round, but that was not the case. According to CBS Sports' Sam Vecenie, "Williams had a rough combine, not measuring out well, not testing out to be the elite athlete many anticipated, and not performing well in the 5-on-5 settings." He's unlikely to be selected and appears headed for the D-league. Had he decided to return to the Hoosiers, he would be a huge piece on a team poised to make a deep run in the Big Ten. Instead he will likely toil on the long bus rides and empty arenas in the NBA's minor league.

Daniel Hamilton, UConn

Daniel Hamilton is certainly an impressive all-around talent, but at 6-foot-7 with limited explosiveness, his 33 percent shooting from beyond the arc won't cut it at the professional level. The lean sophomore wing is currently ranked as the 88th overall prospect by DraftExpress, making it very unlikely he gets selected June 23. With a proven NBA player Kevin Ollie as his coach at UConn, Hamilton certainly would have been better served with another year under his direction. The Los Angeles native scored 12.5 points and ripped down an impressive 8.9 rebounds per game during his second collegiate season, but will need to add substantial size and drastically improve his shooting to be a professional player.
