It know it may seem to be a non-issue with some but there is something I noticed this year that caused me to wonder. Every time they show a coach calling plays on the sideline they almost always cover the lower part of their face with the play sheet. When they show Gase he raises the sheet up to his chin but his lips can easily be seen. I assume the reason coaches do this is to keep other teams from reading their lips so that they can gain an advantage. Maybe it's overblown but I'm just wondering if anyone else noticed this and if it is something to be concerned about or not?
