I actually like gritty finals more than most people. You can feel every pass mattering. But yeah, if you're judging purely on spectacle then the semis usually clear.
That previous streak is what makes this one interesting. It is not that finals are always inherently sterile, it is that football trends shift and this current period has rewarded control much more than chaos.
This is one of those stats that looks random until you think about incentives. Finals are not played like normal knockout matches. They are played like disasters waiting to happen.
Good stat because it also explains why the semis live longer in memory. More matches, more swings, more goals, less fear. Finals are usually about who blinks first.
