@ossobuco,
My only experience with a young football team was when some of the guys in my grade school 8th grade class, the last year of elementary school back then, were high up there in some Chicago catholic school league of age appropriateness... high up re all-city, or all-city in my memory. All of those guys were bright, but I don't think they would have pulled that. Thus my thinking the video a possible construct. Then again, it looks real.
