Would definitely not be 0-5. The WAC went 0-8 in 9/7/02.
Editor's Note: Thanks for that research and I'd agree that was a really bad day for the WAC. But, I still maintain that the Big Ten's 0-5 showing on New Years Day 2011 was the worst day ever for a conference. The reason is that your date was early in the regular season. My date was all New Years Day Bowl Games -- much, much more significant games.
