That's pretty much what you get when you try to survive against a defensive team like the Heat without running any plays. Miami spent the entire 2nd half standing comfortably in place on D, watching Garland dribble the ball and paint himself into a corner time and time again.
Brad and AC made a great point about the Heat being a veteran team that can play "loose but sharp", can't remember their exact words. Their ball movement was something we can only dream about. It always had a purpose. That is how you find an open shooter in today's NBA. However... as a team, you need a certain mindset for it to work. Everyone has to buy in. We had that in the 1st half of the season, but it's dead now.
Part of the reason is Rubio going down, but it's mental too. You often hear the announcers saying that our guys should be moving more, particularly when Garland has the ball.... but in this sport, you need a framework, a basic idea for movement. You can't just run around like a headless chicken. Right now, guys are not moving because the whole "offense" is predicated on reacting to Garland's improvisation. They're watching and waiting. The trouble is, so is the other team. And that means they're resting.
Every time, literally every time Mobley got the ball into one of his spots, had some space and a few passing options, good things happened. Brad was exactly right when he said that he simply must touch the ball every single time down the floor. Garland has to give up the ball earlier in the shot clock, play off Mobley at the high post, and trust Evan to hit cutters. There's two playmakers out there and one of them just happens to be 7 feet tall. DG has to accept it and JBB has to realize it.
