rolling short snap

[Robert Goodman]

At times it may be easier for a snapper to learn to roll the ball back a short distance than to develop a separate aerial snap to a back at short range. The ball is not left on the ground any longer than needed for the back to pick it up. Suppose you see this in a game and have not been warned by the coach. Would you treat a snap rolled a short distance to a back, if it's a consideration under the rules they're using, as a planned loose ball in the vicinity of the snapper?

What if before the game in a coach's conference it was explained to you that the rolling short snap was a regular technique they use, not to make it seem to the other team like a foul-up, but just to deliver the ball?
