Kyrie Irving — who has a decision to make next month on whether to opt-in to the final year of his Brooklyn contract — sat down for the latest “I Am Athlete” episode. He lifted the lid on a host of topics, including saying the Cavaliers would’ve stayed together longer and won more if he’d been more mature. “If I was in the same maturity line and understanding of who I am, and I look back, we definitely, definitely would’ve won more championships, because there would’ve been a better man-to-man understanding about what I’m going through. I didn’t know how to share my emotions,” Irving said. “I didn’t know how to do that. So instead of sharing, I isolated myself.”
