Durant and Irving are really good friends. I could see them wanting to play together.
But I also don't think Kyrie is willing to leave the Celtics to make that happen. He's made it clear multiple times that he wants to resign and stay long-term, but he is tired of the questions.
That's why I think Anthony Davis and Kevin Durant will be Celtics next year, with Kyrie, Smart, Horford, Williams, Baynes, Ojeleye, Rozier, rookies, and MLE/vetmin role players (Morris?).
I think those personalities would work really well together (other than perhaps Rozier who may want a starting job). If that happened, I think the Warriors and the Pelicans would quickly become my 2nd and 3rd favorite teams.
