Hayden Gray, an undrafted guard out of UC San Diego, led the nation in steals and was named Defensive Player of the Year in his conference.
The Celtics have added one of college basketball’s top defenders to their Summer League roster. Hayden Gray, a 6’4 guard who played at UC San Diego last year, was the Defensive Player of the Year in the Big West Conference and led the NCAA in steals.
Gray averaged 11.2 points, 3.3 assists, and 3.1 rebounds per game last season, shooting 47.9% from the field and 41.8% from three. Most impressively, he averaged 3.1 steals per game.
Out of most guys who will go R2 I like Hayden Gray more than damn near anyone
7.2 BPM (5.3 DBPM lolol) 5.7 stl% is insane. He has elite ball hawking and steal generation + Quick hands and gusty anticipatory skills, great fundamentals, feel and motor etc.
