Getting rid of the automatic qualifiers based on the criteria they have used in recent years is a great idea. I'm surprised it took them so long to eliminate this qualification (although they suspended it for the abbreviated 16 team NIT a few years ago). The previous automatic qualifier rule (any team that finished first in the conference regular season but didn't get picked for NCAA tournament) was a dumb rule because 1) some of these teams were really low rated and 2) they interpreted this rule quite literally so that if two teams from a lowly conference tied for first place in the regular season, they both were automatic qualifiers. This automatic qualifying rule resulted in more deserving teams (from both P6 and non-P6) not getting into the tournament.
However, I don't think they went far enough. How about NO AUTOMATIC QUALIFIERS? A tournament called the National Invitational Tournament shouldn't have automatic qualifiers.
