One of those guys is possibly the best defender ever, a consistent 3+ win player coming off a 5 win season. The other is also an above average player, who was still an average player in a down season coming off consecutive 3.5+ win seasons. Seems like a silly thing to nitpick over. Among that core is the world's best player, who automatically makes it a good core all by himself and Justin Upton who is pretty damn good himself.
