LEAGUE DID IT RIGHT. PERIOD.
We (read I and my team mates) went through this EXACT thing a while back. Points, pinfall, and wins were used as a tiebreaker, and my team moved on.
LOSING team filed a protest to the USBC about it. The USBC DIS ALLOWED our win, and mandated a rolloff to determine the winner.
In the event of a tie, ANY tie, WINNERS MUST WIN, AND CANNOT BE "AWARDED" THE WIN USING OTHER PROTOCOLS.
