This is absolute nonsense are you know it. Curry doesn't go missing, he has to deal with more defensive attention than any other player in the league, it's half the reason why they lost in the Finals last season because the Cavs were forcing the ball out of his hands with traps/doubles and letting players like Barnes beat them, which he failed going 5-32 in the last three games. Harden fails because his skillset and style of play isn't conducive to winning in a PS climate. Harden has a passive/protect his shooting%s type demeanor; relying on getting to the line and building rhythm through easy scoring opportunities (whereas Curry has a far more developed scoring repertoire with a chucker mentality). Once you those things away from Harden, he isn't shyt. Curry never has had those problems. Even when entire defenses and schemes are centered around forcing the ball out of his hands, he still finds ways to score. Now just imagine if entire defenses were centered around stopping Harden, like they do with Curry. He would fall right off a cliff.
And don't take about Harden not having the luxury of disappearing and letting his coach team find a way when shyt like this has happened -
5-20 shooting, digging his team into a19-pt deficit hole in an elimination game, and he stays on the bench why he watches his team come back in the 4th quarter to keep their postseason alive. That's NEVER happened to Curry.
