Actually the game manual are updated more often than people think. To the opener, some of the new stuff like the salary floor will be on the game manual soon.
On the other hand, there exist paragraphs that have had no relevance since season 3!
For games older than season 3, the coaching rating is an indicator of the quality of your shot attempts compared to the average quality of the shot attempts you should be able to get with the talent you have on the floor. A good offensive gameplan will give you a high Coaching rating, and a good defensive gameplan will make your opponent's Coaching rating lower. The All-Star Game will continue to list Coaching rating as well.
Considering this notes something that is used every season, and also is used in the archives, how does this not hold relevance?
