Washington, who participated in the NBA combine, posted a video on his social media accounts Wednesday that ended with the words "I'M BACK." The 6-foot-7 Dallas native will be the Wildcats' top returning scorer and rebounder next season after averaging 10.8 points and 5.7 rebounds as a freshman.
Vanderbilt and Gabriel later announced they would stay in the draft after receiving positive feedback.
Injuries limited the 6-9 Vanderbilt to just 14 games, but he averaged a team-high 7.9 rebounds with 5.9 points per game as a freshman. He did not attend the combine but says in a release the input he received during the draft process confirmed "that my time is now."
The 6-9 Gabriel was not invited to the combine but said in a video on his Twitter account that his dreams of being a professional "are that much closer to reality" because of the feedback. He averaged 6.8 points and 5.4 rebounds last season.
