Well, if I were an NFL type trying to max the bottom line, I wouldn't waste the Packers/Bears on the opening game.
I'd pick a game that involves two serious contenders, but if you're going contender game, then I'd avoid rivalry games. Rivalry games can be marketed any week, especially early in the season. (Sometimes not late in the season if, say, the Bears, turn out to be bumblers.)
I'd pick a game of possible contenders OR a game of rivals. But not a game that, at lest potentially, could involve both. Its a waste of resources.
And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.
Romans 12:2 (NKJV)
