Pick N roll or Moving Screen

[Jimgolf]

Jurassic,

Your first reply said ... "Coach, pivoting and then using their backsides is illegal. The screener has to hold their position on the "pick" part of a "pick 'n' roll" until they feel the contact, then roll. Or "roll" without contact. If they pivot and roll before the contact, it's usually an illegal screen. Whether it gets called or not is another story."

I think what TigerBBall is asking is after contact, can the screener maintain contact with the defender, by pivoting, and thus keep the defender from catching up with his original assignment. In other words, what can the screener do after the screening contact has been established legally? Obviously, the screener can roll away from the contact, but can the screener legally move while maintaining contact? IMHO, the screen has ended and determination of whether a foul has occurred now follows normal guidelines, i.e., displacement, unfair advantage, illegal use of hands, etc. Or is this blocking? If so, why is there a difference between this and boxing out for a rebound? And if I'm misunderstanding the whole discussion, I apologize.
