To leave Landry and Shula off is utterly rediculous.
Two of Landry's losses came against the team considered the greatest of all time by a combined total of eight points. One of those games (Super Bowl X), Dallas was a team in transition at that. The other Super Bowl Dallas got screwed in.
And if Charlie waters doesn't graze the laces of the Morrell pass to Mackey, or Duane Thomas doesn't fumble on the 1 yard line, or Morton doesn't throw that errant pass at the end of the game, Dallas would of won Super Bowl V.
How much closer can you get to being 5-0 in Super Bowls?
Landry's coaching in Super Bowls were magnificent.
