I don't know of all the talkin' heads you are referring to, but when I watch some of that stuff, Dickie V, Jay Bilas, et al they do very much include 'Zaga in the upper tier group. For those that don't it probably is because 'Zaga is missing a trip to Final Four on its resume'.
But, take a step back and remember who we are talking about: the media. You expect "consistency?"
