You made some excellent choices, but I have some different choices (marked by ***):

Dallas: Ferragamo to Waddy. 1979

*** NY Giants: 31-3 in 1970. Fond memories of a game that I watched on TV 50+ years ago.

Philadelphia: 29-24 to get to Super Bowl. 2001

Washington: 19-14 in 1974. My first playoff win as a fan

Atlanta: We beat them 59-0 some time in the mid to late 70s

*** Carolina: 34-21 in 1999. Rams clinch the division on the way to the Super Bowl.

*** New Orleans: 45-28 in 1971. Wilie Ellison breaks the record with 247 yards on the ground.

*** Tampa Bay: The 1979 NFC Championship. I was there, and it launched the Rams into their first Super Bowl.

*** Chicago: 34-12 in 1999. Marshall Faulk's 204 yards receiving was key to reaching the exclusive 1000/1000 club.

*** Detroit: 21-10 in 1983. The sun was just starting to shine on the Eric Dickerson golden age. He had 199 yards rushing following 192 the week before.

*** Green Bay: 27-24 in 1967. One of the top five games in the history of the Rams.

Minnesota: 49-37 in 1999 playoffs

Arizona: Last year's playoff game. Being up 28-0 in a playoff game is a rare feeling for a Rams fan

San Francisco: Goes without saying.

Seattle: Negative seven yards. 1979
