The Rockets' GM, who has lost two centers to serious injury in the last few months -- Dikembe Mutombo and Yao Ming -- has used Facebook to help charm a free agent replacement. His target? Dwight Howard's backup in Orlando, Marcin Gortat. This was posted on Daryl Morey's Facebook page shortly before midnight: Meeting in a few w/ Gortat.Send a note to him NOW at rocketsfanslovegortat@gmail.com. He will receive. Show him how much we want him in Red!
