Me personally  I don't like to assume to much ,  Because when you assume its most likely wrong in a  cartain way.   I we can  create a theory of that..  I reduces  FG%..    A lot fo factors will be playing  a part in that too.
 I saw a guard player on the market like  that , I think  you or the other managers was discussing about having a very little Jr./r and  sb  and defense skills  a few comment back. Those players are perfect for  2-3 zone./LI type of  style of play.
  Sb  can  work depends on  who your facing. I think you still  need some ID  to make I  more effective.  Guard with  Sb?? That's a new way of play.   Its not hard  to find  that kind of player . some manager mess up youth and scrap him for cheap.
