Update: Shaquille O'Neal posted a video online indicating his plans to retire. In the brief video, Shaq says to the camera, "We did it. 19 years, baby. Want to thank you very much. That's why I'm telling you first, I'm about to retire. Love ya. Talk to you soon." Shaq was certainly a letdown with the Celtics, but he is certain to join the Hall of Fame.
