Face Guarding or not??

[Warrenkicker]

I would say that face guarding would involve the intentional moving of the hands or arms to hinder the vision of the other player. Having a player's vision hindered by a head or a shoulder, even if intentional, would be a very hard sell to any coach or official. If this player were running down the field and, without making contact on the receiver, the ball hit him in the back or head then I would say that the defender made a great play without even knowing it.
