Kyrie Irving reiterated Friday he is thrilled to be part of the Boston Celtics’ tradition and plans to re-sign with the team when his contract is up after the 2018-19 season.”I’m happy here,” Irving told reporters. “Every single day is at an all-time competitive high. What more can you ask for from an organization than taking a chance as far as getting me out of Cleveland? Really taking a chance regardless of whether I signed back or not.”They had the same attitude. They just wanted to show me what being a Celtic is about, and that I was going to come around, and I absolutely did. I believe in it. I believe in the franchise.”Irving revealed at a gathering of Celtics season-ticket holders at TD Garden on Thursday that he intends to re-sign with the team, despite previous reports of the contrary.He said Friday that one season in Boston, which ended early with knee issues, wasn’t enough to convince him to stay with the Celtics. But he now is certain, he said.”I needed just some time to kind of be back in Boston and feel great about different things I wanted to explore in my career,” Irving said.He said he dreams of his No. 11 hanging from the rafters one day, joining the retired numbers of legendary Celtics.
