The big problem there is, does they have team chemistry in the court? We all know that they are great player but we all know also that cury,thompson,Durant and green use to handle the ball and im wondering how could they execute perfectly with no score competition or ball jealousy on all of the said players, but well if thet really make sacrifice and purely share the ball and make it rotate until it reach to open man well theirs no doubt that they will be the most dangerous team in the history of NBA and provably they will beat their very own record last season on most win team.
That's why it's bad if you have all clutch players on the floor. If that is the case, Head Coach will be the one to mixed all possible chemistrys that compatible on the floor.
Kerr can test out first those three clutch for about 3-4 minutes then see how it will goes.
