Caldwell isn't the only coach who looked lost on Sunday. Plenty of other coaches had just as miserable a weekend.
Peyton is the undisputed leader of the Colts and may be the first person to win Most Valuable Player by sitting out a season. Manning's value goes beyond his physical capabilities. He does not need to have someone tell him what to do, he is the ultimate leader.
He is the coach on the field and he would probably be served to be the coach off it as well this season. Manning could go into coaching after his career is over. He has the incredible ability to read things on the field as they happen and adjust. Much more so than the coaches who follow in this list.
