block/charge article

[rainmaker]

I just finished reading the block/charge article on the eReferee "front page." The author keeps talking about the defense giving the dribbler one step of distance. Where does he get that from? It totally contradicts what I've been taught! Which is that you don't have to give the dribbler any time or distance at all. You just have to be at a spot and in legal guarding position before the dribbler gets there, even if that "before" is only a millisecond. Am I wrong about this? I know there won't be any hesitation to correct me if I am!!!
