A few things bothering me.
First, how easy Detroit is switching when Cleveland sets a ball screen.
There was a play last night where Cade was on Harden and Harris on Mobley. Harden was just crossing mid-court when Mobley set a screen where Cade and Harris just switched without Mobley even touching Cade. Why not try to fight through the screen? You are 45 feet from the basket. Better yet, blitz Harden and use the mid-court line as a third defender and try to force it out of his hands or him turning it over.
Second, the lack of double teams.
I understand they don't want to double because of Cleveland's three point shooting. But Detroit has multiple guys getting beat on the perimeter which causes them to rotate and leave three point shooters open anyway. Send the double before the defender is beat. It gives you a shot at a turnover. But more importantly, it allows Detroit to dictate a little more how the rotations will go.
When a guy is beat, the closest defender has to come off of his man to help. You don't get to pick who that is. If you double, you can pick which Cavs player you come off of to send the double and most likely you're picking one of their lesser 3PT shooters. Slight advantage, Detroit.
