"Chuck Noll said, 'Pressure is something you feel only when you don't know what you're doing.'
That's how I feel. I get prepared. I prepare as hard as I possibly can.
Sure you feel nervous, you feel anxious, but I don't feel pressure because I feel that I have done everything I could to be prepared for that game.
There have been plenty of games where I have said that I wish that I could have this throw back or I wish that I would have seen that linebacker, but it just didn't happen.
But I have never left the field saying I could have done more to get ready for that game.
That gives me peace of mind.'' - former Indianapolis Colts and Denver Broncos quarterback Peyton Manning
