Kyrie and Davis on BOS equals Boston Celtics as the 2020 NBA champions.
But, as the OP stated, Kyrie has nothing but bad feelings towards Boston, deservedly so. I see him going elsewhere.
The smart basketball thing to do; not the armchair basketball fan thing, not the fan whom is a fan of players more than "His team," thing, but the smart basketball move. The smart thing to do is to move everything for Kyrie & Davis. History shows team with a AD & Irving wins. Teams without that type of talents usually does not.
Every other emotional move is not basketball related. It is feelings from grown men who are too invested in other grown men, and maybe should get outside, or a girlfriend....
Gilbert could not stand LBJ, but brought him back because it was the best economic move for Cleveland, & basketball move overall. LBJ eventually did what us Cav fans knew he would, leave. His heart was never in Cleveland, but we have something to show for it.
Every Cav fan knew he was not finishing his career in Cleveland being the Hollywood star he is. Us Cav fans are smart; we were burned once, so we knew no star was a "Lifer." However, we wanted to get at least one title out of out superstars.
Mission accomplished. We do not care about being a "True Cavalier." Can you get us to were we want? Ok, fine, good enough for us.
