A play that should make the list but probably won't is Garo's 51 yard FG outdoors at Metropolitan Stadium, mid 4th quarter early in 1972. The unbeaten season never would have reached talking point stage minus that unlikely kick. The Dolphins trailed 14-6 and had been outplayed and out hit all afternoon. Miami likely would have sagged if the game remained 14-6, and lost routinely. Keep in mind there were no 2 point conversions at that time.
That kick jumpstarted the comeback and shifted NFL history.
Another overlooked play is Morrall's deep crossing pass to Warfield, mid 4th quarter of the opening playoff game of 1972. The Dolphins trailed Cleveland 14-13 on a dreary overcast day and the Orange Bowl crowd was stunned and silent. Our passing game had been inept all day. That single play, a leaping catch by Warfield, awakened the team and the crowd. Miami scored on the drive to pull it out, 20-14.
Interesting project but I have a feeling it will understate the critical plays from the early '70s. That's only natural, since that era is now so distant.
The Bokamper/Theismann play from the 1983 Super Bowl also needs to be on the list. Miami was the inferior team but that play could have twisted the result in our favor. I've been thinking of posting that play on YouTube. It doesn't seem to be there. So far my YouTube videos have not been yanked but a friend warned me the league is touchy about Super Bowl footage.
