Brook and Robin Lopez will both leave Stanford to enter the NBA draft.

Brook was the 7th player selected in RealGM's most recent mock draft and is assured of being a lottery pick. Robin is projected to be a late first round or second round selection.

"This has been a very difficult decision for me because I really enjoyed my two years at Stanford," Robin Lopez said in a statement released to the AP. "I have always hoped I would have an opportunity to play in the NBA and I feel now is the right time to make that dream a reality."

"After a great deal of thought and discussion with my family, I feel it is the appropriate time to enter the NBA Draft," Brook Lopez said. "It is the dream of every basketball player to play and succeed in the NBA and I feel I am ready to take on this new challenge."
