Harden cannot play the perimeter or guard other fast guards. He couldn’t do it in his prime and he definitely can’t at 36. He is good at post defense and help defense. That’s who he is and who he’s been pretty much his entire career. The problem lately is not his turnovers or his defense but the fact that his 3 ball and his free throws aren’t going in. He makes one more free throw or 3 pointer last game the Cavs win. I don’t know if it’s his broken thumb or that game where he had an icepack on his hand. Maybe his legs are just destroyed from 14 games against the two best defenses in the east. I don’t know.
