Winning the draft lottery does not guarantee that a team will come away drafting the best player of the class. Throughout the course of NBA history, there have been many great players who received the short end of the stick on draft night.
Over the past few years, the Houston Rockets have managed to find several diamonds in the rough in the second round. Chandler Parsons, Isaiah Canaan, Nick Johnson, and most recently Montrezl Harrell. All exceeded their draft night expectations to become a vital member of the Rockets rotation at one time or another.
