Excerpt from the article in the link:
Hakeem Olajuwon, a key part of the Rockets’ recruiting efforts to land Howard and a large part of the festivities on Saturday after Howard signed, will rejoin the Rockets in an official capacity for the first time since he spent the final season of his career with the Toronto Raptors.
Olajuwon’s duties and title are still being discussed and he will continue to spend much of the year at his home in Jordan. But he will work with the Rockets interior players, as he does with big men around the NBA each off season, as a team employee.
“We are going to bring him in as full time as is possible,” Rockets general manager Daryl Morey said on Sunday. “It’s not done, but we have mutual interest to get it done and we’ve have some early discussions. We want him to work with Dwight and Omer (Asik) and he wants to do that.”
Olajuwon has worked with Howard in two off seasons and Howard has spoken often about training with him again, this time as the latest in the line of Rockets All Star centers.
