Honestly, I don't care who it is, if the Celtics can find a way to acquire a legitimate star player (i.e. annual All-Star candidate) under 30, I'm all for it.
Having a star is always better than sitting here in no-man's land pinning hopes on role players and middle of the road picks.
Get the talent, then worry about managing personalities and building a supporting cast, etc. If we really believe the Celts are this amazing historic franchise that's so well run, they'll figure it out.
