I agree with you, Crystalmc, but what seems to happen, is that you get certain (not all)pitchers who do replant, and want to make the arguement that since they dragged their plant foot (look at the line in the dirt, I couldn't be leaping) they are legal. It's really more about the timing of the ball release. And for some reason, most umpires will not call a leap under any circumstances, if the pitcher's foot doesn't leave the ground. If they do get a second push, and many do, even though they might not realize it, it's not legal.
