Was the key to Gibbs' success his unique offensive system?

[dgack]

12th man hit two of my biggies on the head:

1) Halftime adjustments. (Anyone else remember being down 10-0 in the Super Bowl? Yeah, me neither. I just remember us destroying the Broncos.)

2) Sharpness -- few penalties, few turnovers on offense, smart play on both sides of the ball. They were professionals, and took pride in their work.

and my other top Gibbs team quality:

3) They were Believers. Believers in Joe, in the team, in the game. They knew they were going to win, believed it every time they took the field, believed that every offensive series could be a game-winner. This is another way of saying they knew how to win.
