Dwight Howard suspended but why not Rondo?

Today they announced that star center Dwight Howard has been suspended for game 6 against the Philadelphia 76ers for elbowing the 76ers center Samuel Dalembert. The incident occured in the beginning of the 1st quarter when Rashard Lewis made a 3 pointer. When Howard and Dalembert got tangled up down low and Howard swung his elbow. Also, during the game Dwight Howard accidently hit Courtney Lee in the nose with his elbow while jumping for a rebound. After the game Dwight Howard had a response to all of this. He said that it was just part of the game and that this has been a physical series and he was just trying to get untangled with the other player. And in other news they let Rajon Rondo go even though he hit center Brad Miller giving Brad Miller a bloody lip and a broken tooth. Why would they give Dwight Howard a suspension and not give it to Rondo? Howard did less harm to the guy than Rondo. A lot of people thought before that Howard was not going to get anything because he is a superstar. But it was the opposite way around. The Orlando Magic right now have 3-2 series lead and hope to close out the series in game 6 without Howard. While the Boston Celtics also have a 3-2 series lead and Rondo will be playing for them in the clinching game 6. But the Boston Celtics will still not have Kevin Garnett due to injury.
