Actually, I'm kind of clamoring for him to be dealt - if Ainge can get fair value in return. I really like these Big Wing lineups that the Celtics have used a lot this year, and needing to find minutes for Irving and Rozier kind of undoes that, especially if Smart (whom I'd like to see re-signed) comes back. But I'd still rather keep Rozier than deal him just to deal him.
I'm not sure which thread to discuss this in, but those lineups have been a revelation in the playoffs. I'd go so far to say that their success may have altered the Celtics' team-building plans, especially since Tatum and Brown are looking more like potential #1/#2 playmaking options than before. Add in Hayward, and you can make some ridiculous lineups with shooting and playmaking at every position, in which everyone is over 6-7 and huge.
Danny (used as a metonym for the Cs' front office) has been really good at adjusting to situations as they change, rather than being anchored to the past. The clearest case of that was the Kyrie deal, in which he avoided fixating on either IT's past performance or the Nets', and in the process got a step ahead of Cleveland.
Going into these playoffs, it was an open question whether the big wing lineups could score (everyone knew they could defend). Now that we've seen what they can do under pressure, and with the prospect of adding Hayward and more mature Tatum/Brown to that, I'd be surprised if Danny wasn't exploring ways to deploy that setup more often. That would mean that dealing one or both of Kyrie and Rozier is very likely on the table and being explored internally, just because of their price tags and the defensive constraints they impose. Rozier is a plus defender, and Kyrie is decent when healthy and engaged, but they don't let the Cs create these devastating "no weak links" lineups.
So, prediction: if the Celtics make the Finals and take 2+ games off the Warriors/Rockets and look competitive in the process, Kyrie gets dealt.
