That analogy really doesn't work. Footballs awesomeness comes from the play by play not necessarily the TD. Smash's awesomeness comes from the play by play not necessarily the kill.
That quote is hand-picking the most boring scenario of a battle with big blast zones. I could do the same with Melee and its in comparison smaller blast zones where an opponent gets defeated the same way 4 times in a row because the game is too unforgiving. It's just a different environment altogether.
People will simply adapt. It's, for the love of god, not a "real problem".
As for the false analogy, not really. Football's awesomeness comes from both TD and play by play. It's not necessarily anything. Same with Smash.
