I think this dead horse remains dead - but nevertheless:
Name a team other than the Eagles that lost the NFC championship three years in a row.
irrelevant. plenty of teams have made the playoffs 3 straight years without winning a superbowl - which would mean they lost their last game. this does not mean they have a "usual late season let down." you have an agenda, or an axe to grind, or something - go grind it elsewhere.
and incidentally, if memory serves, the raiders lost a conference championship three years in a row. people always forget to mention how the teams that won those 3 games against the eagles fared (2 SB wins and a 3-point loss). must be that weak NFC.
The Rams did it from 1974-76 and the Raiders also dropped three in a row from 1973-75.
They lost to Green Bay in the title game in 66 and 67, Cleveland in divisional playoffs in 68 and 69, lost to the Colts in 70, and won the Super Bowl in 71.
Of course, both Buffalo and Minnesota have lost four Super Bowls without winning one. Where the Eagles have been doesn't really matter. It's where they go from here. Of course, the Eagles are evil, so I'm hoping for a Patriots victory.
