at this moment KD might kill the cohesion of Klay , Green ,Curry got going.  Too many cooks kill the stew ...see This years Celtics  

GS big three are play n great team Ball minus KD .  I don't think small doses of Cousins will hurt them if he returns. when the moment calls for him .  He does not dominate the ball.
Not that GS would not win with KD .   I just think they are revved up for the challenge to dominate with the original core .....KD re entrance kinda kills the current mojo . 
At this moment in time GS is smoother running team minus KD.
