It would surprise me that's for sure. Fox, CBS, and ESPN pay BILLIONS of dollars to the NFL for broadcasting rights of their games. If the NFL decided to go to PPV, they would never make back the same profit margin as they are now. Even if there was potential to get that much money (and there isn't), it would take a HUGE act from them, plus everything could suddenly go down the shitter if people don't actually pay for the services. Too risky.
