Honestly, what is people's problem? Out of all the starters, SAR is probably the most efficient guy for the money he is playing. He is only averaging 16 ppg because he is the FOURTH option. He scores more than Miller AND gets higher percentage. The system is against him, yet he does more than could be expected. What more do you want from him?
As for his defense, can you really blame him? He was never known for his blocking, but you can't really ask him for KG, Webber kind of performance. You don't hear Dallas fan complaining about Nowitzki's blocking, do you? But he still plays hard on defense. The breakdown on Kings' defense has always started with Bibby and Peja from outside, which dominioes into a disaster inside. If you play basketball, even with just your friends, you'll know the inside defense can't hold without much outside defense. Bibby lost his intensity, and Peja has never shown much effort on guarding his man. They let the man in, and at the end things look bad for inside players. I feel sorry for Miller, too, since he is at least an average man-to-man defender. Before blaming SAR and Miller, blame Bibby and Peja first.
As for the rebounding, I admit, SAR has lost his intensity over the years with the losing teams. Kings' so far losing season probably doesn't help much either. Beside, one of his greatest points is also his weakest link: he is too un-selfish. In a league full of Artests, he is a lone man, who doesn't try to hog the attention. He boxes out his man, but rather than jump for the ball, he makes sure his man stays away from it. I guess he is someone who plays it safe, too much for his own good.
People complain he is no Webber. Well, he certainly isn't being paid like one, nor being played like one! SAR is getting only a fragment of what Webber got paid, and the coach is using him as only the fourth option(even with Bibby and Peja's blunders over the months) when Webber was THE choice on the offense. I think Kings doesn't have the right to demand such performance out of him since he is being underpaid, underplayed, and underappreciated. To be honest, I want to see him be more selfish. Hog the ball once in a while. Jump the ball and get that rebound out of the guy's hand, even if he is your teammate! Post down low and scream for the ball, and don't pay heed to Adelman shouting you to stay on the top of the key. I really miss the Vancouver SAR, who played with such intensity that even Karl Malone was impressed. Curse the Hawks and Blazers, may you never get to the playoff again before SAR!
