question on rule

[jentzd]

Well, like I said before, I really want to avoid using 'ground rules' or 'house rules' and practice the right way.

How is the dribbling path to be interpretted in this case? Is it allowed to go through the defenders forearm? Through the defender? By extending this logic, what is there to prevent the player with his ball setting the end of his dribbling path right under the basket, and keep inching his way backwards until he gets there?

The specific stuff i am referring to here is found at: http://www.nba.com/analysis/rules_12...av=ArticleList
Section B, part1, Exceptions 1-3.

What constitutes defensive position? The wording itself is vague. How should the forearm legally be used to preserve defensive position?

Thanks Again,
