LAS VEGAS — Terry Rozier was miles away from the vocal disappointment in Boston, when his name was announced as the 16th overall pick on draft night. While the people at the Celtics’ draft party booed and groaned, Rozier, fully dressed, jumped into a pool.

“When my name got called, people were just screaming,” he said. “I couldn’t hear anything. I was so happy just seeing how my family felt.”

Danny Ainge heard. He was downstairs from the ballroom at the Seaport Hotel, but the reaction by the season ticket-holders and guests could be heard and felt.

The Celtics president of basketball operations knew from experience not to worry about the response.

“Some of the best draft picks that I’ve ever been associated with were ones that weren’t received well,” Ainge said. “The first one that comes to mind was Steve Nash, when I was coaching Phoenix. People wanted us to take John Wallace from Syracuse. The fans went ballistic. It was just not well received at all.”

Nash was a steal at 15 in the 1996 draft. Wallace went three picks later and had an undistinguished career with five teams. (That was also the draft that saw the Celts take Antoine Walker at six, while Kobe Bryant went at 13.)

“Another I remember is when we drafted Shawn Marion, and everyone thought for sure we should have taken Corey Maggette, who turned out to be a good player also, but Shawn obviously has had an amazing career,” said Ainge, whose Suns got Marion at nine (Maggette went to Seattle at 15 and was traded that night to Orlando). “Those are just two picks that stand out in my mind.”

Rozier seems to understand the whims of a fan base — particularly one that was expecting a more familiar name to come rolling off commissioner Adam Silver’s lips when it came time for the Celtics’ pick. But he’s ready to change some minds.

“Listen, I get it,” said the 6-foot-1 guard. “I know the Boston fans are all about their basketball. They probably were looking for a big name that they had projected.

“But I would say that the fans will end up falling in love with me. I give 110 percent, and that’s in practice and every game and everything. So I think those boos will turn around to be yeas. That’s my goal. I know the people here are serious about their basketball, and I am, too. I think it will all turn out fine.

“You never want to hear your name get booed, but it’s fine. I’m not going to let it bother me because I know what type of guy I am. I know the fans are going to end up falling in love with me and how I play the game.”

Rozier already has Ainge’s affection, and Ainge is unaffected by exterior opinions.

“You can draft the person that the people think you should draft, or you can draft the player that you think is best,” he said. “Ultimately it comes down to who plays the best, and I have a strong belief in Terry — not just his talent, but who he is as a person and his work ethic. His athleticism and makeup are what really attracted me to him, and I’m really excited about him.

“I don’t think it’s going to take long for our fans to understand how good a player he is. Terry’s just a fierce competitor and a great athlete, and those kind of guys are some of my favorites — you know, Delonte (West) and Tony (Allen) and Avery (Bradley). I love those kind of guys.”

Rozier believes he fits in very well with that crowd. And although he isn’t all that large, he thinks his frame can handle the chip on his shoulder. Much like Paul Pierce going after each of the nine teams who passed on him in 1998, Rozier has some things he’d like to show those who picked ahead and those who think he went too high.

“All my life I’ve been playing like that,” he said. “The first 15 teams that passed on me … you know, I’m just excited to be in this position. I’m ready for this.”

Interestingly, Rozier has come across as a calm and relaxed sort thus far.

“I just know that every time I step on the court I’m another person,” he said. “I’m locked in. I want to win. I’m competing as hard as I can.

“I’m not an angry person off the court, but I want my opponent’s best, and I’m going to give my best. I’m just all about competing.”

And changing the draft night opinion of Celtics fans.
