RJ Barrett entered the collegiate chapter of his basketball career as the No. 1 player in his class, so it’s no surprise that the chapter was short.

The one-and-done announced he will declare for the NBA draft via Instagram and Twitter Wednesday, and will likely be followed by Zion Williamson and Cam Reddish in the coming days.

"It was amazing to play for Coach K, play for the brotherhood. It was a dream of mine to play at Duke ever since I was a young kid. It's also a dream of mine to play in the NBA and have great success there," Barrett said in the social media video. "I'm looking forward to coming back and supporting the Blue Devils any way I can."

Although Barrett had a historic season, his greatest competitor for the top pick in June happens to be his roommate. With the unique athleticism and charisma that Zion Williamson holds, it’s likely that Barrett’s gameday carpooling buddy will come out on top, as many mock drafts show Williamson as the first pick, with Barrett following as a close second or third along with Murray State's Ja Morant.
