Bag the OOB Spot?

[ljudge]

I attended a quarterfinal as a spectator today and watched an out of district crew work a local game. The LJ bean-bagged the spot every time the player went OOB. Frankly, I think it looked like S**T! When I was a LJ I got the spot with my feet and usually did a half turn to watch the out of bounds area for nonsense and either my R or BJ was there to help me but I never bagged the spot and moved from it (to cover the OOB players) 2-3 yards beyond the sideline like I saw today. Do any of you do this as a mechanic? It looks sloppy to me and it's something I never used or saw used in varsity football until today.
