I really do not have a problem with the Bengals not taking advantage of the new blackout rule because as much as we may not like it to admit it as fans it's probably the right business decision, especially with the way tickets have been selling early on this year. My plan would not only give fans an opportunity to watch black out games in the local market but it would also potentially increase revenue for the teams pretty significantly. If a games is not sold out and subject to the black out rule the NFl should allow fans and businesses the opportunity to buy the game on pay preview.
Here's my suggestion,
The cost for a residential household would be the price of the cheapest ticket to go to the game, in the Bengals case that would be $40. Look at it this way if you invite 3 friends over to watch it with you the cost would only be $10 bucks a piece and you could watch the game in the comfort of your own home. The cost for a business (bar or restaurant) would be the price of the most expensive single game seat, which would be a suite ticket, in the case of the Bengals that would be $270 bucks. Every bar and restaurant in the area would be foolish not to jump on that price for the potential increase in business.
In the end we would all be happy. The team is happy because they are bringing additional revenue and the fans are happy because there would be alternative cost effective opportunities for them to watch the game.
