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…
They have to lose two times to be eliminated, same as every other team. I.e., the lower bracket finalist has to win two full matches over the upper bracket finalist in succession in order to win the tournament, but the upper bracket finalist need only win one match.
