Not having to play extra matches or getting side selection is not a big enough advantage for someone who NEVER lost. What would they get out of it?
Would a bracket reset be good for viewership? Might be way too long for most people, and would lessen the stakes of the first set. If a team started with a 1-0 advantage that could result in a 2-0 dud of a final. I just don’t see many good solutions here…
Who gives a fuck about them and what they get.
Double elim is better for the competition overall, as it mitigates a whole bunch of shit things about single elim, eg unlucky draws, single bad days, uneven brackets, civil wars, coin toss side selections (we’ve seen matches where the side selecting won every game, so the coin toss winner won).
It might not be good for them this year, when they’ve won every game, but it will be good for them next year when they slip up. It all evens out in the end.
