I am just going to enjoy the playoffs and appreciate them for what they are, as this team could look different next season (whether that's good or bad, remains to be seen.)
As for the offseason, I wouldn't be surprised if Kyrie stays or goes. It's not hedging, it's just reality as it seems to be a very fluid situation which could certainly be impacted by the outcome of the playoffs. Even all of the "experts" have thrown in disclaimers saying Kyrie and Durant could change their mind a million times between now and July 1st.
If Kyrie did leave, I still think Ainge goes after Anthony Davis and wouldn't be surprised if Bradley Beal is the potential back-up plan.
I also think the only 3 guys that are just about certain to be back next season are Smart, Hayward and Horford.
