Trying to be balanced is also directly related to out thinking your self. Let's see we just ran Play A and got 30 yards, lets run Play B and then Play C and not come back to Play A again for a few weeks.
That's how you out think yourself. You make the opponent stop you. Not the other way around.
Remember when we were running all over everyone a few years back? 2003 2004? We had a total of SIX running plays. Teams knew it was coming, teams knew they couldn't stop it. They knew which side, they knew when, how and no one could consistently stop it.
I miss those days. I liked being able to predict the play back then, now I don't like being able to predict the play because it doesn't net the same result.
Back then, I knew the play because it was what worked.
Now, I know the play because its not the play that worked earlier in the game. What? 3rd and long? DRAW! What? Brandon Jackson is on 2nd down? SCREEN PASS.
