Seems like there is a certain cutoff point where your NET alone can get you in regardless of the quality of your non conference schedule. Once you are below that line it looks like you need to have at least a couple non-conference Q1 and Q2 wins. The Big12 scheduling allowed for many of their teams to have very high NET rankings without having any non-conf Q1 or Q2 wins. I think UVA made it over a couple other bubble teams because they were 2-2 non-conference Q1/Q2 with vs say an Indiana Stat that was 0-2. So you either have to be in a conference that piles up the non conference wins in general so you have a shot to have a very high NET regardles of overall record/quality of OOC wins OR take advantage of your limited opportunities for OOC Q1/Q2 wins. And also blow out the Q4 teams you play, especially OOC.
