NHL Network is in the process of running every Cup clincher for the last 35 years and this week's games are 1980-1984, with the Isles winning four of them, before the dynasty is finally stopped in 1984.
The games air at 8:00pm on NHL Network (with repeats overnight and the following morning at 9am (8am on Saturday)) . (These appear to be full game broadcasts --not condensed to 2 hrs. Tonight's 1980 Game 6 is 3 1/2 hours long)
For less nostalgic fans, relive the "Shawn Bates gane" from the 2002 playoffs. That airs tonight at 8:00 on MSG+.
