Pros: The Cox Convention Center or Bricktown Ballpark would provide a more controlled environment as well as more amenities for fans. Crowd size could be limited, and admission could be charged and concessions sold to offset the cost of the facility. Fans would also have access to bathrooms.
Cons: First, a facility would have to be available. Second, additional big screens would have to be brought in, which would be an added cost. And finally, it could be shutdown by the television network. NBC recently blocked the New Jersey Devils and the New York Rangers from having watch parties during the Eastern Conference Finals. The reason? They would zap the ratings. And if a network is concerned about watch parties in markets that big hurting ratings, you have to think they'd be keeping an eye on a smaller market like Oklahoma City.
