I'm starting to think you don't know what people mean when they criticize Bonner. Bonner's whole benefit is that the offense plays insanely well due to the spacing his three-point shooting supplies. That's why he was called the +/- King. As soon as the March (it's been getting earlier each year) rolls around, his shooting goes south, and the Spurs' can't adjust to the lack of spacing.
Green's production isn't based on three-point shooting. He's a really good help and individual defender, and he rebounds very well for his position. He boxes out well, and he provides timely plays. That did not dry up during the stretch run. He was a big part in the Spurs' 20-game winning streak. In the first two rounds of the playoffs, he (and Leonard) was absolutely destroying their compe ors. Green was a major part of the comeback in Game Three against the Clippers, and he played critical defense on Paul to close out Game Four. In the OKC series, he hit a shooting slump, which he obviously let get to him in other aspects of the game. But he was still the defensive-rating king. Bonner never had that impact when his shots don't fall in a series.
Green and Bonner are nothing alike. Jefferson and Bonner were, maybe. But Green has made too many clutch plays to say he shrinks under pressure.
