True story. I went to the first home preseason game against the Texans this year. The Cardinals have a new pregame feature, the "keys to the game," a bullet-point list of things the Cards must do to control and/or win the game. It's displayed on the scoreboard and spoken by the PA announcer at full volume. It is done after team introductions, while both the Cards and their opponents are on the field.
It's a fine enough idea, getting the very casual Arizona fans at least mildly interested in the game. The problem is, all of the "keys to the game" were written in the negative.
For example:
"Don't let the other team score first," instead of "Score first."
"No turnovers" instead of "Control the ball."
That sort of thing. So the players are standing out there, after all the anthems, introductions, fireworks, etc., and some douche PA announcer is telling them about all the things that could go wrong. Really gets a team fired up.
The starting defense promptly gave up a touchdown on an 85 yard drive, after a turnover on downs.
