I don’t think you can do that anymore. Refs are looking for that and with the circle under the basket, if the defensive player is outside the circle he gets the charge, if he is inside the circle is a block every time. With instant replays and multi-angle cameras, the refs get feed back fairly quickly. Where PGs have an advantage is when being guarded outside and the defensive player cannot use a hand check like they did before, if they do it is called a foul every time.
As far as blocking, Withey was special insofar as he could jump straight up and down without leaning and his timing was amazing, a result of his volley ball playing, no doubt. Look at the game a couple of years ago when Nerlens Noel had a record number of blocks and I posted pictures that showed that he was fouling while blocking in most of the plays and he was not called for that.
