We'll say not counting the Super Bowl or NFL Championship games.

I'll also not include any Steelers games among my favorites.

My other favorites:

1992 AFC Wild Card - Bills 41, Oilers 38 OT
...The Comeback

1990 NFC Championship - Giants 15, 49ers 13
...Great battle at Candlestick. Montana knocked out and 49ers denied a potential three-peat.

1987 AFC Championship - Broncos 38, Browns 33
...I wouldn't mind watching this game again. You always see "The Drive" but they rarely show this game and was a classic. Browns fell behind 28-10 but rallied to tie it 31-31. Broncos went ahead on a TD by Sammy Winder. Browns tried to answer before the Byner fumble.

actually here we go

1982 NFC Championship game "The Catch"

49ers 28
Cowboys 27

Propelled the 49ers into one of the greatest runs in Pro Football and the Cowboys went the other way for a while.

Bills/Oilers is the one I think of when I think of great playoff games.
