Yes, when going left you need to keep the left in position to accept his right. Braddock neutralized Baer's right while moving left by jabbing his shoulder- jab to draw the right, the second jab to disrupt it. Remember, too, what Haislet said about this. That circling right is the safest and should be most often used. If you consider the course of boxing, it has gone down a road where fighters circled this way and that to where they only circled left, to where they don't circle at all.
Another way Norton had success against Ali was by making Ali move to his own right- Ali's right. Ali, other than for the right against Liston, rarely if ever punched while moving right. Today, 99% of the time you see an orthodox fighter kove right, he is bailing out with no intention of punching. This is a result of poor footwork.
