Daryl Morey is a smart guy. Williams is the best player in the trade... headache or not, moving to Houston could be good for him. If it doesn't work, he'll still be the better trading chip. There's always a GM "smarter" than the rest, that realizes the true potential in every head case, and he's talented and young, a great athlete... Daryl would be the best replacement (in a distant future) for Danny Ainge.
Unless Joe Smith is a good mentor to Character and Bynum, I don't get it for the Lakers. They'd better pick up some guy from the DL, if I recall correctly, the last time I saw Smith play he had lost not one, but several steps.
Let's hope the Celtics are injury-free from now on, lack of health is the only rival for the men in green.
