After the Brooklyn Nets locked up the No. 7 seed in the Eastern Conference with a 134-126 win over the Indiana Pacers on Sunday, Kyrie Irving smiled as he discussed the impact the play-in tournament has had on the NBA since its inception last season. “I think somebody’s in the back room hip-hip hooraying whoever created the play-in tournament,” Irving said after going 15-for-20 from the field and scoring 35 points in Sunday’s regular-season finale. “Because last year you get Steph [Curry] and LeBron [James], this year you get me and KD going against the Cavs in the play-in game. And then you have in the Western Conference, Minnesota and the Clippers. So I guess somebody’s in the back room saying this works.”
