Boston Celtics president of basketball operations Danny Ainge has liked Terry Rozier's summer league showing and believes the guard is making a strong push for a spot in the regular season rotation.

Appearing on ESPN2's broadcast of the Celtics game against the Cleveland Cavaliers, Ainge answered a list of questions, including one about which guys have a chance to earn minutes next season.

"I think that Terry Rozier has made a great case for himself for next year," Ainge replied. "He's been our best player from the first day of training camp this summer. He's been terrific for us. He was a good player last year in training camp, just didn't get a lot of opportunities because of our depth at guard. But I think he's winning a spot."

The Celtics have a need for more creation after Evan Turner signed with the Portland Trail Blazers, and Rozier looks like he may be ready to answer that call. He hasn't just put up big stats at summer league -- he has also looked thoroughly in control of his talents, like a player who is beginning to figure things out.

Another Celtics youngster who could be in the mix for perimeter minutes is Jaylen Brown, the No. 3 overall pick in last month's draft.

"I like the integrity with which Jaylen has been playing with," Ainge said. "I like that he defends, he rebounds, he passes. He's a complete player. I mean, he's got to become a better shooter -- and he will because he'll put in the work. And he needs to become a better finisher around the rim and all those kind of things. But at age 19 with his body and athleticism and willingness to play defense, I think he's going to be a terrific player."
