Some people need to chill the **** out here. The fact of the matter is Boozer and Okur as defenders are practically interchangeable. Boozer had some more physical ability by way of agility, but was a few inches shorter, and Okur tried a little harder. The net result is practically the same; crap. Boozer was not a bad post defender and horrible in every other way, and Memo is the same.
And there's no question in any non-homer's mind that Memo would be the worst defender on this team, all things considered. And before Homer is money has another conniption fit, that does not mean that Memo's net contribution will be bad because he definitely brings value to the court (at home) on offense and is usually a good (not great) rebounder.
