Took from the Warriors reddit. Data went all the way back to 2013. Have not validated. But here you go. https://i.redd.it/u04uf39n1xw01.png
thanks a lot for the info! Based on this, it looks like Harden's shooting right around his career(44%) with Klay guarding him. But I read somewhere that he was only shooting around 38% against Klay. It probably came from some made up stat from ESPN...
This season Harden has an offensive win share 11.6 and defensive win share 3.6. Klay has an offensive win share 3.2 and defensive win share 1.8. Harden is three times the player Klay Thompson is.
So between points and assists, the Rockets came of of Klay on Harden with points somewhere between 45-55% (depending on 3pt ast vs. 2pt ast)
I dont think discussing this is meaningful. Numbers show Exum is a good defender, but when Exum was out due to injury, Harden still played like scrubs. Nobody could stop James Harden but himself. Unfortunately Harden always presses the turnoff button himself in playoffs.
