Marvin Bagley Jr. has announced his decision to leave Duke to declare for the 2018 NBA Draft.

"I can’t believe the time has come for me to say this but I would like to announce that I will be declaring for the 2018 NBA Draft," wrote Bagley on Instagram. "First off I want to thank Jesus for putting me here and allowing me to show my gifts that he has given me. I want to thank my family and everyone who has been in my corner since day one, the support has meant a lot to me. I also want to thank those who doubted me and continue to doubt me, it only pushes me to get better every single day. I learned a lot this year on and off of the court and I’m thankful for the opportunity. Thank you Duke!!!"

Bagley is expected to be one of the top picks in the draft.

R.J. Barrett has been named the 2018 Naismith High School Boys' Player of the Year.

Barrett becomes just the second Canadian to win the prestigious award and first since Minnesota Timberwolves forward Andrew Wiggins captured the honour following his 2013 season at Huntington Prep. 

Last November, the ESPN No. 1 recruit committed to join Duke University next season.
