If the kids and parents signed a photo release like the one I mentioned I signed every year I played sports from 3rd grade until I graduated high school, and the school signs off on him selling the footage, then he would indeed have everything he needs to sell it.
It would be no different than the standard photo releases almost every production company uses when they shoot interviews or even when using paid talent. It releases the school and anyone affiliated from liability in regard to the photos or video.
But again, who would spend the money it would take to get attorneys involved regarding something like this? The foogate certainly can't be worth enough to fuss over.
