This is just an x's and o's question not an absolute, not a pronouncement, just a question. Once again it has been confirmed by David Mayo on MLive that Lawrence Frank is using Terrence Williams soley as PG.

Now what I was wondering if by some chance Williams beat the odds and played well enough to force the Pistons to cut a guarenteed contract (totally unlikely) Could he facilitate the offense while at the same time being allowed to defend against the 3. Does your offensive assignment coincide with your defensive? In general do nba players have to defend their counter parts on opposing teams?

I only ask because as others have pointed out williams is not a strong shooter but according to assesments from his draft (such as nbadraft.net and draftexpress.com) he has the physical talents to defend the one-three. I just wonder if there is a scenario where he is assisting to better perimeter shooters like Knight or English or Villanueva and then coming back on the defensive side using his athletiscm to defend people like say Danny Granger, Paul Pierce, etc. Any insight would be appreciated.
