He CAN shoot. He proved it last night and the other night in Cleveland, when he made some very big shots down the stretch. The key for Miller is shooting the ball within his comfort zone, which is about 15 feet and in. He's actually pretty accurate from there.
Andre Miller can't stretch the defense. That's what people are talking about when they say Miller can't shoot. Teams sag off him and double Roy/Aldridge and Miller can't make them pay for it. It's a problem.
