Experimental Rules, Exempt Tournaments

[Alaska Ref]

Our BP Top of the world Classic Basketball Tournament will get under way in Fairbanks, Alaska on November 16th at 7PM AST.

This year there will be 2 experimental rules;
1) The use of the "International Key" (Trapezoidal Key)

2) NBA restriction ARC of 4 feet, you know the dotted arc in front of the basket.

The folks keeping stats will turn over the numbers to the rules committee, (i have not seen exactly what they are asking for yet!) and the coach's and referee's will also have to fill out reports on the rules impact from there perspective's.

I also understand that the NCAA and Dr. Hank Nichols have instructed at referee clinics that the game will be called much tighter then in previous years. (Screening, Off the Ball and Post Play.)

So what do you think???
Why are they testing these rule changes?
Do you think the rules committee will adopt the changes?
What do you think of the "Emphasis" on calling a tighter game?

Looking foreword to your reply's
