Curry/Durant high PNR is like 10% of their offense at-most even in the playoffs.
The only reason Kerr has been using that play so much of late is because the Warriors defense has been ass meat for a while now. He's used it in desperation.
You're much more likely to get killed by Curry's off-ball movement and efficient use of floor space than that play.
But when it comes down to it, if Durant sets a good screen, the only way to contain it is to hug Durant and not let him roll on a screen. Basically cheat.
And obviously there can't be a delayed switch from Durant's man.
Curry typically resets instead of isolates but come playoff time he's probably taking everyone off the dribble.
I HIGHLY doubt a combo can contain that but CP3 + Luc Mbah a Moute is a decent bet. You'd have to bet on Paul guarding Durant on a switch.
Mbah a Moute is really good. Gives no space and can still contain penetration without help. Long with excellent closeouts. Not a bad combo.
