You can accuse the conference of lying if you want, but there is no evidence to support that. No one has said the conference declared them disqualified and then changed their minds. The most outspoken person on this issue, Kevin Dresser, explicitly said the Big 12 had NOT told them anything. Until I hear or see better evidence, I will believe the people at ESPN who asked the Big 12 directly for answers, then reported it to their audience and cited their source.
