This feels interesting for the same reasons scorigami was an interesting thing. There are many ways to get a final score of 21-18, and I really wonder if this is a first.
Nice. That reminded of this post I made last week where Denver had 13 points, having scored no touchdowns (2 safeties and 3 field goals), and Seattle had 9 points (1 TD with a failed 2 point conversion and a field goal). I always love weird scores or scores that make you go "how the hell did you get 21 points with no touchdowns?"
