How do you know they'll never create it? Maybe they're experimenting to see how the team reacts, or how the other team reacts.
What would you prefer? For them to game plan and blow their load in the preseason? To show teams the type of offense they're going to use in a meaningless game? To appease paranoid fans no less? By the way for the last half of the season there was a key piece of the offense missing.
If the coaching staff is smart which I believe they are, they have a good idea of what they have and they don't need to show it off to appease the fan base or the media in a meaningless game. That's why I have no respect for ESPN, they have programming to fill so they burn a segment on the teams who haven't scored an offensive touchdown...in the preseason...
And this is said every preseason so forgive me for this Buffalo cliche...How well did the Super Bowl teams look in the preseason?
