Mike Conley has joined the Boston Celtics with a clear objective: help a new-look roster compete for a championship while providing veteran leadership to a team that underwent significant changes this offseason.

Conley officially met the media Tuesday alongside Paul George, Brad Stevens and Joe Mazzulla after arriving in Boston. The veteran point guard signed a one-year minimum contract with the Celtics after spending the previous four seasons with the Minnesota Timberwolves.

For Conley, the decision to choose Boston came down largely to the organization’s established winning culture.

“It was fairly quick honestly,” Conley said of his free-agent process. “But you know, the main reason, you look around the league, there’s very few organizations and teams that you look at that honestly are trying to win every year.”

The Celtics’ history also played a major role in his decision.

“The culture here in Boston speaks for itself,” Conley said. “The championships, the banners, the fan base, all that encompasses all of that.”

Conley added that the opportunity to join a franchise with Boston’s history, while working with Mazzulla, Stevens and the Celtics’ players and staff, made the decision straightforward.

“I just wanted to try to do it here,” Conley said. “Have an opportunity to play for such a storied franchise and have an opportunity to be a part of it and a tribute to that and do what I can to help try to get that goal of a championship which would be my first opportunity to try to do that.”

The championship pursuit carries particular significance for Conley and George. Neither veteran has won an NBA title, and Conley believes that shared experience can add urgency to Boston’s new group.

“The urgency I think that even myself and Paul got to bring for this team is two guys who haven’t had a chance to win a championship yet,” Conley said. “So, it’s that sense of urgency that maybe reignites that for the guys who’ve been on this team who’ve already won it.”

Conley also sees himself playing an important role with Boston’s younger players. The Celtics retained several young contributors from last season, including Payton Pritchard, Jordan Walsh, Baylor Scheierman, Hugo Gonzalez and Neemias Queta.

“I still got a lot left,” Conley said. “I still can do it on the court, off the court, but leadership is one thing I know I can bring.”

Conley specifically mentioned working with Pritchard during workouts and sharing different perspectives on the game.

“I’m not quiet about it,” Conley said. “I’m just going to say, ‘Hey, do this next time or look at this or look at this option.’”

The 38-year-old Conley averaged 4.5 points and 2.9 assists in 54 games for Minnesota last season, but his value to Boston extends beyond his statistical production. Across a 19-year NBA career with Memphis, Utah and Minnesota, he has averaged 13.6 points and 5.5 assists while shooting 38.7% from three-point range.

Boston finished 56-26 last season before losing a Game 7 to Philadelphia in the first round. The Celtics subsequently traded Jaylen Brown to the 76ers and brought in George, Conley and Mitchell Robinson as part of a substantially reworked roster.

For Conley, the changes represent a fresh opportunity.

“I still got a lot left,” he said. “I still can do it on the court, off the court, but leadership is one thing I know I can bring.”
