The NFL was just f**king in love with Brett Favre and the Packers after Dallas began its downward spiral during the mid-90's. -We were screwed out of that game harder than the 1992 NFC CC game.
But I'm definitely sure we would have derailed Elway's 'fairytale' moment, but the reason we couldn't get past the Packers in the 90's was because of 2 things:
1. Mike Holmgren.
2. Green Bay's Tampa 2/Zone defense (The WCO-killer).
