Guess I better clarify, then.

Given: Team X is in eliminations by some means.
Given: Team X is undefeated after eliminations.
Then: Team X won the event.

BTW, I thought of another case that would make my previous statement untrue:

Given: Team X is in eliminations.
Given: Team X is undefeated going into the eliminations.
At some point, Team X wins a match (we'll assume undefeated at that point too), but is too busted up to continue. Team Y is brought in as a backup to continue, and the alliance drops their next two matches.

Team X is still undefeated. (You could argue that as a member of the alliance, they took two losses, to which I say: They weren't on the field, were they? That's like saying that the [pick your baseball team] lost and a pitcher who wasn't playing that day got the loss as well as the pitcher who pitched the loss.)
