I wouldn't say that it's his fault Houston regressed this season, but that the criticism on him for being a low energy defender and playing for the whistle are valid. That's not rlly about who he's got around him
Spurs/Warriors run equal opportunity offenses and Harden is ball dominant, so he would be a poor fit on either team in replace of their top players
Playing for whistles, if you want to call it that, works for him. He was top 2 in scoring two years in a row. Still don't understand how that's a knock on him talent wise. Defensively, yeah.
Harden has to be ball dominant because if he isn't this team falls apart. He's pass first unless he's on fire or no one else is making shots.
