That is entirely correct and is the basis for the "jump-stop" move. Probably the move taken the most advantage of in basketball in regards to the travel, especially out front with a guard. Watch how many steps the guard takes when he catches the ball with his back to the defender and is up in the air and is allowed to take as he re-establishes himself facing the defender out front. I count 3-5 steps sometimes. They called one at a key time over the weekend, but really had no choice as after the long steps on the catch, the guard also slid his feet.
Then watch for the extra hops steps the guards and post men get inside on the so called jump stop. They pitty-pat many little steps in stopping and many little steps in taking off [Duncan & Hansbrough]. That is what drives the coaches crazy but actually is the hardest for the officials to actually see. We watch tape and show it all the time, but officials just are not looking down at the feet. Reason--the lead official on the baseline is looking thru the players for contact, looking into bodies on their shots for shoves & hacks. Plus he is usually too close to see the feet. Your 2 officials out front--trail on strong side & slot on the weak side without the ball are the guys that are away from the post & can see the feet, but they don't have the post as their "primary" area. All 3 officials are not supposed to be looking at the ball, just one set of eyes, maybe two if in the middle of an area. By staying in their primary areas is how you get the illegal picks, hedges, bumps and all the "off the ball" stuff they are supposed to get. Hopefully one might be looking up and can see the foot shuffle and help out the lead with the travel call.
