The thing I found odd about this case is that the football coach's behavior is blatantly unBiblical.
“And when you pray, do not be like the hypocrites, for they love to pray standing in the synagogues and on the street corners to be seen by others. Truly I tell you, they have received their reward in full. But when you pray, go into your room, close the door and pray to your Father, who is unseen. Then your Father, who sees what is done in secret, will reward you." - Matthew 6:5-6
Going to the 50-yard line to pray in front of an entire stadium after a freaking football game and then going on media to talk about it constantly was just about the most blatant violation of his edict possible.
