Its a really stupid ruling imv. Now any coach, or player, can decide to "pray" to any God or all Gods, or anyone they think could be a God, or not a God, on the halfway line at the end of a game. This should be fun. I wonder if he had been a Satanist, would SCOTUS have found in his favor - or if he had been an Imam coaching on the side, but who whipped out his prayer mat, pointed East and thanked Allah (silently), but with players, if they wanted to join in. I'm not so sure.
Thankfully, both the Satanist and Imam and Wiccan Witch and anyone else, can all now feel free to do so.
Stupidity.
