I figured as much when Okafor played that game in Boston. They were getting another look at him. I think Danny genuinely wants a rim protector. The big daddy, of course, was Cousins. But Okafor is just a kid. A big kid who can score in the paint. He is young enough to be taught the other stuff. He has the body, and can block shots.
I think it's possible a Butler deal could also bring a Lopez or Gibson if the Bulls get Okafor. They are looking for more offense up front.
