With the college basketball season in the rear-view mirror and the NBA Draft on the horizon, it is time to lay out the full rankings for the Top 40 players. From one-and-done teenagers to sixth-year seniors, there is a wide range of players at every position. The NBA Draft is scheduled for June 26 and 27, spread across two days for the first time this year. Before that, there are several key dates to watch. The deadline to enter came and went on April 27, with the deadline to withdraw set for June 16. The next step in determining which players will decide on their professional future is the NBA Combine, scheduled for May 12-19 in Chicago, Illinois. Teams will get a closer look at the measurements of the top prospects and see borderline players go through various workouts.
