From a business standpoint, it's probably a good quick way to fill lots of empty seats. I can see why it's inticing, especially for minor league teams. Sell to the churches big blocks of seats. Easy sell, because it's a case of follow the leader. It's Church Night Out (though that makes for a long evening for those clean-livin' folks).

You'll be getting a crowd that presumably will be well-behaved (though unlikely to buy a lot of beer).

On the other hand, how many of these people are going to become sports fans/repeat customers? Instead of watching the game, they could wander about handing out pamphlets or something. These people don't miss a trick when it comes to captive audiences.
