I have cleared out all of the sources but two.  I left the Sentry source because it is available online and the Beacon Journal source because it was closer the the event and I assume makes the claim.  I also removed the references for the school not having won since 2006.  In order to keep the reference current someone will need to post the results here every year, which is not worth the effort.  It is an easy claim to refute if false and not worth the effort to maintain the references.
