“It went well,” Brown said of his workout. “[Celtics president of basketball operations] Danny Ainge is a great guy. We have a connection now that I think is surreal. I like Danny. He was a physical player back when he played, a tough guy. We have the same mentality.”

The Cal product said Sunday he felt he made a good impression during his workout with the Celtics on Wednesday. Brown, a 6-foot-7-inch swingman is projected as a top-10 pick, but wants more.

OAKLAND, Calif. — Draft prospect Jaylen Brown is trying to prove he’s worthy of the Celtics’ first draft pick, No. 3 overall in the NBA Draft.


In a Wednesday press conference to announce his and Brad Stevens’s contract extensions, Ainge said Brown had a “very good” workout.

The Celtics are expected to work out a plethora of players when trying to decide whether to use the No. 3 pick or package it in a deal for a veteran player. Brown is considered raw, but freakishly athletic.

Unique to the Celtics’ workout is the grueling full-court run that tests the endurance of prospect at the end of the session. Brown said he flourished in the race.

“It was great; I definitely finished first,” he said. “I don’t think anybody was in my realm but it was tough. Doing it after the workout was tough.”

On his conversations with Stevens and Ainge, Brown, 19, said: “It was great. Brad knows a lot about the game and [I] was like a kid in a candy store, taking the experience head on and that’s what it’s about for me.”

And on Boston, Brown said: “It seems nice. I definitely liked it the short time I was there. I can get used to it.”
