It is, but only 4 were expected by seeding, and KU was clearly a wreck, so that was expected. Really just lost one more than expected in Baylor (though no one else performed above expectation). The media would find a reason to question unless the Big 12 just blew everyone's doors off, and their opinion is worth about as a much as a fart on a windy day.
Since there's been so many blow outs, if BU pulls it off last night, they would question why the Big 12 couldn't do the same.
