Travel call during spot throw in.

[Nate1224hoops]

My understanding of that rule is that once you have established your "spot," then a player may step with one foot in any direction. If both feet are moving or in motion on a spot throw-in, then it is a violation. It's not called as a traveling violation but a spot throw-in violation. But it's basically the same concept as traveling. Is this right? Any comments.
