You have to be able to get KD the ball. If you really don't trust his ability to get open from TA, post him up and just have KD get a lob over the top.
At least we started Harden in the OT.
at Durant, "why the **** he ain't get me the ball?"
Like I said earlier....there's three other players not taking the ball out for the Thunder. Use two of them to set a double screen for Durant to the ball side-corner, then the third to set a down screen for Durant around the FT line elbow. Or, at the very least, use all three players not named Kevin Durant to set a series of screens for KD.
