I remember the 92 NFC Championship Game. The Niners just score to cut the lead to 24-20.
About 5 minutes remain (I think). Norv Turner calls down to Jimmy Johnson and says, "You want us to take time off the clock."
Jimmy replies, "I want to score!" Translation: call plays that will get us in the end zone. And that's what Norv did.
None of this mealy-mouthing, "We'll if this is the case, then you do this. But if this, then do this. But make sure you don't make a mistake."
No, Jimmy says, "Let's make SURE we win this game. Do what's necessary to win the game."
And when your players believe your coach is about winning, they'll adopt an attitude that they want to win.
