Newly introduced Boston Celtics guard Kemba Walker sits down with ESPN's Jackie MacMullan to discuss various topics including how he felt when he arrived in Boston, and why he chose to join the Celtics over his former Charlotte Hornets. Walker says he has not talked to Kyrie Irving since replacing him at point guard as Irving signed with the Brooklyn Nets. Walker also discusses players from the Celtics that had an impact on him before he chose Boston including Jayson Tatum and Jaylen Brown. He says this is the first time he's played on a team that has any kind of expectations and says he's going to enjoy the pressure put on him immediately.
