Well, I was certainly including you when I later said that there are probably a half dozen posters here that believe he is overrated and/or should be traded. You have suggested both several times and you may even be right. But while his efficiency isn't where we want it, there are very good reasons for it namely that he's been playing injured and out of position. Even still though, his true shooting percentage is .570 which really is not horrible, especially since he so rarely gets fully open or single covered. Klay Thompson, for example, even though he's surrounded by tremendous players, is at .568.
If I were going to rip Booker, it would be for time missed and time playing when he shouldn't because of injury limitations. And then I'd go after him for his absurd turnovers and his referee confrontations. I know that's probably him just trying to be a leader and sticking up for his teammates but he's too invested in it. He needs to calm down, shut up, and just play basketball for awhile. But I'd also point out that even with his shortcomings he's putting up positive numbers that are almost unheard of for a 22 year old.
