I would still say LeBron is head and shoulders above the rest of the league, and Tier II are guys like: KD, Westbrook, Harden, Curry.
So if I get the first pick for a best of 7 series right now, it has to be LeBron, he has basicly been the MVP since 2008.
But KD is scary, his length is atrocious, offensive skill beyond this world, BUT in his OKC days, you could see the immaturity in his game in late game situations.
IMHO I would take Curry over him as well, so in my book:
1. Lebron
2. Curry
3. KD
4. Harden, Westbrook(just to many turnovers, and bad defense, and decision making to be better that that)
