“winners win probability is low throughout the game” is one of the three factors influencing the composite score. (if it were the sole factor, the patriots falcons bowl would be the most exciting game by far)

The other two factors are “win probability closeness to 0.5” and “win probability changes”

You’re right, that awful rams super bowl won the “closeness to 0.5” category, which is why it’s ranked top 5

And yeah, it’s a fun cool project but not perfect. The best way to assess super bowl excitement is still to sit down and watch!
