BOSTON — The Cavaliers traded Kyrie Irving for the eighth pick in the 2018 draft.That’s how last summer’s blockbuster trade shook out Tuesday, when the Cavs won the No. 8 pick in the June draft at the NBA Draft lottery in Chicago.Cleveland was in the lottery because it owns the Brooklyn Nets’ first-round pick for 2018, thanks to the franchise-shifting trade in which the Cavs received two picks (including that one) and three players from the Boston Celtics for Irving.The Celtics and Cavs, of course, are also playing Game 2 of the Eastern Conference finals against each other on Tuesday.”Finally we know where we are and it was nerve wracking, obviously, going through that process, but, we’re pretty comfortable where we are,” Cavs general manager Koby Altman said in Boston. “We realize how deep this draft is. We’re excited about the potential of this pick and the player we can get at eight.”The Nets finished with the eighth-worst record (28-54). The Cavs had a 2.8 percent chance of getting the No. 1 pick and a 9.9 percent chance of landing one in the top three.Nick Gilbert, 21, the son of team owner Dan Gilbert who is recovering from February brain surgery, represented the Cavs on stage. Nick Gilbert’s bowtie was made with a piece of the Cavs’ home floor from the 2016 championship season.
