I am not trying to rain on anyone's parade, but you DO know that the coaches have repeatedly asked fans NOT to take video footage at practice, right?
From the sounds of it, they are closing practice after this week and one of the reasons is that was given was that video and discussions involving formations and schemes are being put out on the internet for opposing teams to pick up and review. I personally love the videos and practice reports, but I also don't want to give our opponents an advantage against our O, whether it is a real advantage or perceived.
And before you jump down my throat, I know the video linked above is not one of those videos in question. It would be hard to determine the formation or even the personnel from the linked video.
