Shaq has had a very good career but he's one of those athletes that has relied on a lot of natural talent. I don't think he's worked very hard to improve his game over the years. He would rather do commercials and have fun than work on his free throw shooting. It's that simple. He could improve his free throw shooting if he worked on it but I don't think he really cares. He's got championship rings and a lot of cash so I don't think you'll see him taking extra free throws after practice.
The Cavaliers missed 17 free throws tonight and that's why this team won't go anywhere. Shaq is hideous from the free throw line and Lebron James is a lousy free throw shooter also. The Cavaliers have lost a lot of games over the last few seasons because they can't shoot free throws.
