Backcourt violation - 3 second violation

[Shades of Gray]

Freddy,

No, you are a couple of thousand posts short and a couple of thousand miles away from me and TWLA.

Thanks for the replies but I am still having trouble trying to understand why this should be a backcourt violation in the example I described. As I stated earlier, I don't doubt TWLA, Nevada Ref, etc.'s statements that under the rules this is a violation, but I can't see why it should be. For example, if the player did not lift his non-pivot foot but merely dragged it, this would not be a violation, correct? So why should it be a violation for merely picking the foot up and setting it back down? Also if the player is dribbling the ball while staddling the line, the foot in the back court can be picked up and put down, right?

Maybe I should just go with "That's the rule, live with it", but I would like to hear some logical explanation of why the rule is written the way it is. Thanks.
