A sport event you have watched

Let me talk about my favorite sport, basketball.As far as I know, the NBA is the most famous basketball association in the world which is made up of 30 teams from America and Canada. The organization was founded in New York like 60 years ago.I still remember that my roommates and I watched the NBA games in dormitory nearly 4 years ago. At that time Yao Ming was still in Huston rocket which millions of Chinese basketball fans really pay close attention to it. In the playoff games, Huston Rocket met Los Angeles Lakers and their best player Tracy McGrady was injured. This means that Yao Ming had to undertake more obligations. But unfortunately, before the end of the game Yao Ming was also hurt by Kobe. He lay on the ground and felt really uncomfortable. But he did not quit the competition and came back to the play ground. Finally, He inspired his teammates to win that game.
Actually, that game left a deep impression on me.

Also, "like 60 years ago" is a very informal way to write this. you could say instead "about" or "around 60 years ago"
