I think you have to take some chances sometimes, but you can't be dumb about it.
For example, the Benard pick-6. Sometimes it's best to throw it away or take the sack. Early in the game if it isn't 4th down, no need to expect every play to be for positive yardage.
But I'm not ready to turn into a dink and dunk offense either. If you want to open the running game, you've got to have some downfield threat now and then.
