The Miracle on Ice had so much substance behind it that it'll likely never be topped. The political atmosphere + the underdog story + it being played in the US makes it difficult to top.
I will say, I was rooting for Edmonton in hopes to watch McDavid dominate. It's incredibly fun to watch.
I admired Brady in the same fashion. Hell, I had multiple Bills-Pats games I went to where Brady and co. would send us to the parking lots by the 4th quarter. Over time, I grew to admire his dominance in spite of him kicking our ass.
McDavid is going to be the best player of his generation, so I'm just going to sit back and enjoy the show!
