As a fellow French guy, I would say this about Diaw: Make sure he wants to play for you if you trade for him. Everywhere he went, he either played great cuz he was having fun, Phoenix with Nash (International atmosphere in that team as well...they could talk abt soccer together at least) and San Antonio with his best friend Tony + Pop to keep him on track and motivated; or he played like a$$ cuz he didn't want to be there and you end up with an overweight cryptic player. "Babac" was raised with a very "do whatever you want to do" education and you can feel it when he is not happy.
To be fair and to highlight that I love this guy, he was and is always motivated when paying for his country!
