IMO this game is a positive for the Blazers.
Yes, Aminu and Harkless shot way over their heads. But CJ and Dame shot way under. Overall we shot 39% from three, slightly better than we can expect. On the flip side, Houston shot 53% from three. Well over their heads.
CJ and Dame's shooting was just variance. You can't do anything about that. That's not what cost us the game. We lost because:
a) We committed about 3 to 4 times as many "bonehead" plays as we did in recent games.
b) We misdefended Harden.
The right way to defend Harden is the way Wes Mathews defended him when we beat the Rockets in the playoffs. He stayed between Harden and the basket. Period. That means backing off as much as you need to, to stay between him and the basket. Stay as close as you can to defend the three without allowing him to blow past you. A Harden 3 is a not shot you'd like to give up, but it's better than two 87% free throws or a kick-out to a wide open 3 pointer, or an easy layup, or an "and one".
IMO Blazers played ridiculous defense on Harden, guarding him super-tight well beyond the three point line. Harden broke that down again and again, beating his man with an open path to the hoop. I don't know why we did that.
