JayDou asked the question today if the Big 12 had even gone undefeated in a week before. The answer is...no!

First of all, it's somewhat unusual for all 12 teams to play a nonconference game the same week. Second, the Big 12's storied history dates back to 1996. Back in the day, some of the teams had preseason kickoff classics, so you had uneven start dates as well.

The closest the conference had come to a clean sheet was in week 2 of 2001, when they went 11-1. Before you jump all over Baylor, I'd like to note that the Bears beat Arkansas State that day, while the Kansas Jayhawks fell to the UCLA Bruins 41-17.

The conference was 10-2 on four occasions (week 1 in 04 and 06, week 2 in 06 and 07) and went 10-1 on three occasions in week 2 (02, 03 and 05).

This info was pretty easy to get to courtesy of James Howell's excellent research.
