NCAA Rules that NFHS or State Associations should try out?

[chseagle]

My reasoning for asking about what rules from NCAA that the NFHS &/or State Associations should adopt is cause of the fact that I had heard after Washington State added the Boys' Shot Clock, it was to better prepare the players to college play. By adopting the NCAA rules for high school play, the players would not be at a disadvantage when it came to playing at the college level, & you'd see more Freshmen playing college level than you do now.

Concerning the questions about the stoppage of clock in final minute after made basket & having to add time, not all scoreboard controls have the capability to do the tenths of a second entry (the operator has to input the next second higher & be precise on when to stop the time).

How many of the rules/regulations that the NCAA uses do the NBA, WNBA, & FIBA use?

As I see it the rules should be universal throughout all levels.
