Barrett will disappointingly remember his last tournament game where he missed the front end of a pair of free throws against Michigan State in the Elite 8 as Duke lost by one.

An Associated Press first-team All American, Barrett announced his decision through social media on Wednesday, April 10, saying "It was a dream of mine to play at Duke since I was a young kid". Including Barrett's triple-double, there have only been four triple-double's in program history.
"After discussing with my coaches and my family, I decided that I'll be declaring for the 2019 NBA Draft".
Barrett recorded Duke's first triple-double since 2006 with 21 points, 11 rebounds and 10 assists in a 94-78 home win over N.C. State on February 16. I want to thank the Crazies and the entire Duke community for everything you've given to me.
